  text: 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.
