An adaptive MLSE receiver for TDMA systems: a hybrid of per-survivor processing and tentative decision MLSE

摘要

An adaptive maximum likelihood sequence estimation (MLSE) receiver employing both the persurvivor processing (PSP)-MLSE and the tentative decision (TD)-MLSE, and selecting either one of them depending on the received signal power is proposed. Thereceived signal power is estimated by using a channel estimate, assuming that M-ary PSK symbols are transmitted. Simulation results demonstrate that the proposed MLSE can significantly reduce the computational complexity with little degradation inperformance, as compared with the conventional PSP-MLSE.
