Abstract :
This paper addresses the optimality of the fixed-delay tree search with decision feedback (FDTS/DF) detector for data without a minimum run length constraint. The evaluation is performed by comparing the minimum distance for FDTS/DF with the minimum distance associated with a maximum likelihood sequence detector (MLSD). Using this distance information, potential improvements through coding are addressed. An alternative realization to the direct implementation of FDTS/DF is considered by examining the detection process in the context of a signal space
