text: Deadwood moisture affects multiple functions of downed logs in forest ecosystems.
They include provision of habitats for xylobionts, additional water stores and
organic carbon stocks. In contrast to Northern American forests, little is known
about moisture variability in downed logs of important tree species within the
Temperate Zone of Europe. Therefore, our study aimed at elucidating this variability
according to species, site and decay class (DC). Measurements were taken by TDR
during two vegetation periods in eight Carpathian natural forests representing
distinct site conditions, ranging from xerothermophilous to subalpine. Downed
logs of \emphQuercus spp., \emph{Abies alba} Mill., \emph{Fagus sylvatica} L.,
and \emph{Picea abies} L., belonging to various DCs, were selected and instrumented
with TDR probes. Species and DC-specific TDR calibration showed the importance
of intrinsic wood porosity. The course of deadwood moisture consisted of drying
during the early decay stage, except for \emph{A. alba} and \emph{F. sylvatica},
and an intense water reabsorption at later decay stages. Average moisture for
all species and sites displayed seasonal trends, reflecting the occurrence of
precipitation clusters and dry periods, as well as short-term fluctuations. Cross-spectral
analysis revealed that both sapwood and heartwood participated in wetting and
drying processes, but only after reaching an advanced stage of decay. New findings
can be applied in interpreting, modelling and predicting deadwood water stores,
habitat properties and respiration.

text: Spectrum sensing has become one of the main components of a cognitive transmitter.
Conventional detectors suffer from noise power uncertainties and multiantenna
detectors have been proposed to overcome this difficulty, and to improve the detection
performance. However, most of the proposed multiantenna detectors are based on
non-optimal techniques, such as the generalized likelihood ratio test (GLRT),
or even heuristic approaches that are not based on first principles. In this work,
we derive the locally most powerful invariant test (LMPIT), that is, the optimal
invariant detector for close hypotheses, or equivalently, for a low signal-to-noise
ratio (SNR). The traditional approach, based on the distributions of the maximal
invariant statistic, is avoided thanks to Wijsman’s theorem, which does not need
these distributions. Our findings show that, in the low SNR regime, and in contrast
to the GLRT, the additional spatial structure imposed by the signal model is irrelevant
for optimal detection. Finally, we use Monte Carlo simulations to illustrate the
good performance of the LMPIT.

text: An alternating optimization algorithm was recently proposed for the K-user
multiple-input multiple-output (MIMO) interference channel. For flat-fading channels
and feasible problems, this algorithm successfully aligns the interfering signals
exploiting the spatial dimensions. In this paper, we consider the case in which
all pairwise MIMO channels are frequency-selective (convolutive), and the users
transmit broadband signals using a single-carrier scheme. Unlike the flat-fading
case, for frequency-selective channels it is necessary to add a spectral mask
in the frequency response of the precoders and decoders to avoid trivial solutions.
We show in the paper that each step of the alternating minimization algorithm
can be reformulated as a convex optimization problem in which the autocorrelation
function of the precoders or decoders is obtained. Upon convergence, a final spectral
factorization stage must be applied to obtain the precoders and decoders from
their autocorrelation functions. Simulation results are provided to illustrate
the performance of the proposed algorithm.

text: This paper studies large multiple-input multiple-output (MIMO) communication
systems with linear precoding and reduced-rank Krylov subspace receivers. We design
precoders and analyze their performance by exploiting large-dimensional random
matrix theory. We first devise low-complexity precoding schemes that can improve
performance of low-rank Krylov subspace receivers in the regime of high signal-to-noise
ratio (SNR). We then introduce a potential theory-based method for analyzing the
convergence behavior of the mean-squared error (MSE) for various transmission
schemes. This method can be applied to a broader range of problems compared to
previous analytical tools. The analysis reveals that the MSE decreases super exponentially
with the rank of the receiver. Numerical examples show that the proposed precoders
can outperform conventional precoders when low-rank Krylov subspace receivers
are used, and that the performance of such receivers can be accurately predicted.

text: Spectrum sensing is a key component of the cognitive radio (CR) paradigm.
Among CR detectors, multiantenna detectors are gaining popularity since they improve
the detection performance and are robust to noise uncertainties. Traditional approaches
to multiantenna spectrum sensing are based on the generalized likelihood ratio
test (GLRT) or other heuristic detectors, which are not optimal in the Neyman-Pearson
sense. In this work, we derive the locally most powerful invariant test (LMPIT),
which is the optimal detector, among those preserving the problem invariances,
in the low SNR regime. In particular, we apply Wijsman’s theorem, which provides
us an alternative way to derive the ratio of the distributions of the maximal
invariant statistic. Finally, numerical simulations illustrate the performance
of the proposed detector.

text: This paper deals with different techniques for linear equalization (LE) of
multipath channels with imperfect channel estimation (CE). We develop a unified
framework based on Krylov subspace expansion, which allows us to compare the performance
of the conjugate gradient (CG) method, diagonal loading (DL), and a hybrid scheme.
Our analysis shows that the DL method generally outperforms its alternatives,
but at the cost of higher complexity. However, we also demonstrate that a proper
implementation of the low-complexity CG method can also approach the performance
of DL. Finally, we show that preconditioning degrades performance when the CE
is poor.

text: This paper considers large multiple-input multiple-output (MIMO) communication
systems with linear precoding and linear minimum mean-squared error (LMMSE) equalization
based on the iterative conjugate gradient (CG) algorithm. Convergence of the CG
algorithm is fast when the eigenvalues of the received signal’s covariance matrix
are clustered, suggesting that mean-squared error and receiver complexity can
be managed with judicious precoder design. In order to accelerate convergence
of an iterative CG receiver, we incorporate constraints on two measures of eigenvalue
clustering into the precoder design. Closed-form solutions to the optimal precoders
are derived using majorization theory and convex optimization techniques. We show
that if there are constraints on receiver complexity, the proposed precoders can
improve performance for large MIMO systems operating over slowly time-varying
fading channels.

text: The Strong Uncorrelating Transform (SUT) allows blind separation of a mixture
of complex independent sources if and only if all sources have distinct circularity
coefficients. In practice, the circularity coefficients need to be estimated from
observed data. We propose a generalized likelihood ratio test (GLRT) for separability
of a complex mixture using the SUT, based on estimated circularity coefficients.
For distinct circularity coefficients (separable case), the maximum likelihood
(ML) estimates, required for the GLRT, are straightforward. However, for circularity
coefficients with multiplicity larger than one (non-separable case), the ML estimates
are much more difficult to find. Numerical simulations show the good performance
of the proposed detector.

text: This paper advocates that the convergent systems property and incremental
stability are two intimately related though different properties. Sufficient conditions
for the convergent systems property usually rely upon first showing that a system
is incrementally stable, as e.g. in the celebrated Demidovich condition. However,
in the current paper it is shown that incremental stability itself does not imply
the convergence property, or vice versa. Moreover, characterizations of both properties
in terms of Lyapunov functions are given. Based on these characterizations, it
is established that the convergence property implies incremental stability for
systems evolving oncompact sets, and also when a suitable uniformity condition
is satisfied.
