ABSTRACT:
A system and method for performing set partitioning to recover M-ary modulated digital data symbols. The set partitioning technique reduces the complexity of sub-optimal algorithms in communications systems such as wireless communication systems utilizing PML, SPML, and APML algorithms. The system and method reduces the number of searches in a system by choosing an average value for the transmitted signals in the system.
