Abstract
The common basis of coherent and differentially coherent detection is considered from the viewpoint of carrier recovery as the estimation of fading distortion. In the differentially coherent receiver a simple estimate of the fading distortion is used whereas the coherent receiver uses the optimal estimate. The bit error rates (BERs) for M-ary PSK (phase-shift keyed) and DPSK (double phase-shift keyed) transmission are calculated using a single method of calculation for both detection schemes. The calculation takes into account nonperfect carrier recovery, cochannel interference, and diversity. The results allow a direct comparison of the two schemes and show that coherent detection is preferable in many realistic fading environments.
