METHOD OF DETECTION OF SIGNAL IN COMMUNICATION SYSTEMS WITH MIMO CHANNEL

摘要

An apparatus and a method for detecting signals are provided. The method for detecting signals in a receiving end having a plurality of antenna in wireless communication system includes performing Minimum Mean Square Error (MMSE) estimation for a transmitted symbol vector, determining a covariance matrix for the MMSE estimation, determining a triangular matrix based on the covariance matrix, and determining accumulated metrics for each symbol vector candidate based on the triangular matrix.
