A Comparative Analysis Between Different Detection Schemes in Flat Rayleigh-Fading Channels

In English We compare the performance of different detection schemes in terms of resulting pairwise error probability in Rayleigh-fading channels. We introduce a unified analysis framework used to compare sensitivity to Doppler and noise. The analyzed methods include: pilot symbol assisted modulation, differential detection, multiple-symbol differential detection and detection using superposed pilot symbols. We also introduce an improved hybrid detection scheme, combining the strengths of pilot symbol assisted modulation and superposed pilot symbols
