Soft-output decision-feedback equalization with a priori information


Soft-output equalizers that exploit a priori information on the channel inputs play a central role in turbo equalization. Such equalizers are traditionally implemented with the forward-backward or BCJR algorithm, whose complexity is prohibitive for channels with large memory. Many reducedcomplexity alternatives to the BCJR algorithm have been proposed that… (More)
