DETECTION OF A COMMUNICATION SIGNAL

摘要

The present disclosure relates generally to communication, and more specifically detection of a communication signal in a multiuser or multiple-input-multiple-output (MIMO) receiver of a communication system. A reliable signal subset (72) and a less reliable signal subset (74) of the communication signal (66) is identified using a reliability threshold test (50). Soft output detection (54) is performed on the less reliable signal subset (74) to produce a first output. Interference cancellation (52) is performed on the reliable signal subset (72), where the interference cancellation is less computationally complex than the soft output detection (54) performed on the less reliable signal subset (74). Then a soft output (56) of the communication signal (66) is determined for use by a channel decoder (42) based on the interference cancelled reliable signal subset and the first output. Aspects include methods, devices and software.
