Abstract: Método y aparato de comunicación digital de decisión blanda. El aparato decodificador (200) decodifica una señal coherente modulada por modulación digital de fase multinivel codificada diferencialmente (DEPSK). Un receptor coherente (101) recibe y, ulteriormente, entrega la señal coherente modulada por DEPSK a un computador métrico (201). El computador métrico (201) genera una métrica de decisión blanda {A ({s (n)) correspondiente a la señal coherente modulada por DEPSK que se entrega a un decodificador de corrección de errores hacia delante (FEC) (107). El decodificador de FEC (107) decodifica la señal coherente modulada por DEPSK según la métrica de decisión blanda {A ({s (n)) correspondiente a la señal coherente modulada por DEPSK.

Abstract: A decoding apparatus (200) decodes a coherent, differentially encoded multi-level phase shift keying (DEPSK) modulated signal. A coherent receiver (101) receives and, subsequently, outputs the coherent DEPSK modulated signal to a metric computer (201). The metric computer (201) generates a soft decision metric @ (@ (n)) corresponding to the coherent DEPSK modulated signal which is outputted to a forward error correction (FEC) decoder (107). The FEC decoder (107) decodes the coherent DEPSK modulated signal in accordance with the soft decision metric @(@ (n)) corresponding to the coherent DEPSK modulated signal.
