Efficient successive interference cancellation decoder for a mimo communication system

Abstract

According to an aspect, method of decoding a set of symbols from the plurality of signals received on multiple antennas of a receiver in a MIMO (Multiple input and Multiple Output) communication system, the method comprises receiving a first set of signals on a corresponding a first set of antennas, receiving a channel characteristics corresponding to the first set of signals, wherein the channel characteristics are arranged in a first matrix form, performing Hermitian transform on the channel characteristic to form a second matrix, wherein the second matrix is a covariant matrix, performing Cholesky decomposition on the second matrix to generate a third matrix, wherein the third matrix is a triangular matrix, performing successive interference cancellation using the third matrix and the first set of signal to generate an estimate of the set of symbols. According to another aspect, comprising the method further comprises partitioning the second matrix into sub matrices that are of the order less than the order of the second matrix and performing the Cholesky decomposition recursively on the partitioned sub matrices.
