Abstract

An adaptive maximum likelihood sequence estimation (MLSE) receiver employing both the per-survivor processing (PSP)-MLSE and the tentative decision (TD)-MLSE, and selecting either one of them depending on the received signal power is proposed. The received 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 in performance, as compared with the conventional PSP-MLSE
