  bibo_abstract:
  - The problem of optimal carrier recovery and detection of digitally phase modulated
    signals on fading channels by using a nonstructured approach is presented, i.e.
    no constraint is placed on the receiver structure. First, the optimal receiver
    is derived for digitally phase-modulated signals when transmitted over a frequency-nonselective
    fading channel with memory. The memory results from the fact that usually the
    coherence time of the channel is larger than the symbol period. Symbols adjacent
    in time cannot be detected independently and therefore the well-known quadratic
    receiver is not optimal in this case. A maximum a posteriori (MAP) detector is
    derived and explicitly utilizes the channel memory for carrier recovery. The derivation
    shows that the optimal carrier recovery is, under certain conditions, a Kalman
    filter. Some attractive properties of this carrier recovery unit (including the
    absence of hang up) are discussed. Then the error rate of several digital modulation
    schemes is calculated taking the performance of the filter into account. The differences
    in susceptibility of the modulation schemes to carrier phase jitter are specified.@eng
