Decision-directed coherent detection in multicarrier systems on Rayleigh fading channels
PK Frenger, N Arne, B Svensson - IEEE Transactions on …, 1999 - ieeexplore.ieee.org
Novel coherent detectors for DQPSK and/spl pi//4-DQPSK on Rayleigh fading channels are
presented. The detectors are based on decision feedback and minimum mean-square error
(MMSE) channel estimation. The proposed detectors may be used in both single carrier and
multicarrier systems. Analytical results in the form of expressions for channel estimation error
variance and bit error probability, both with and without diversity, are derived. The MMSE-
based detector has a significantly lower irreducible bit error probability floor compared to a …
