Propomos um novo esquema adaptativo de detecção diferencial de múltiplos símbolos (MSDD) que possui excelente desempenho em canais de desvanecimento seletivo de frequência (FSF). O esquema MSDD adaptativo consiste em um estimador de canal de mínimos quadrados médios adaptativo não coerente que pode realizar a estimativa de canal sem qualquer atraso de decisão e o MSDD. O algoritmo M é introduzido neste esquema de detecção para reduzir a complicação do cálculo devido ao aumento do comprimento da sequência observada no MSDD. Devido à aplicação do estimador de canal adaptativo e do algoritmo M, este MSDD adaptativo torna possível que a estimativa de canal seja realizada para cada símbolo ao longo de M caminhos sobreviventes sem qualquer atraso de decisão. E o desempenho do SER deste MSDD adaptativo não é afetado pela flutuação de fase introduzida por um canal porque o MSDD e o estimador de canal não coerente são aplicados. O esquema MSDD adaptativo é aplicado à constelação típica de 16APSK, ao (4,12) QAM e à estrela QAM. O excelente desempenho de rastreamento deste esquema MSDD adaptativo sobre canais FSF é confirmado por simulações computacionais.

Abstract: We propose a novel adaptive multiple-symbol differential detection (MSDD) scheme that has excellent performance over frequency selective fading (FSF) channels. The adaptive MSDD scheme consists of an adaptive noncoherent least mean square channel estimator that can accomplish channel estimation without any decision delay and the MSDD. The M-algorithm is introduced into this detection scheme to reduce the complication of computation due to increasing observed sequence length in the MSDD. Because of the application of the adaptive channel estimator and the M-algorithm, this adaptive MSDD make it possible that channel estimation is accomplished for every symbol along M surviving paths without any decision delay. And the SER performance of this adaptive MSDD is not affected by phase fluctuation introduced by a channel because the MSDD and the noncoherent channel estimator are applied. The adaptive MSDD scheme is applied to typical constellation of 16APSK, the (4,12) QAM and the star QAM. The excellent tracking performance of this adaptive MSDD scheme over FSF channels is confirmed by computer simulations.
