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.

Method of detection of signal in communication systems with MIMO channel

A mobile station is capable of detecting a signal in the wireless communication systems using the Multiple Input Multiple Output (MIMO). The mobile station includes an apparatus that determines a vector of signals received by several receiving antennas. The apparatus estimates a channel between transmitting antenna and receiving antenna; forms a channel matrix; establishes, based on the channel state data, an order for detecting symbols transmitted by different transmitting antennas; calculates weight coefficients for detecting the symbols in the MIMO system; detects the symbols serially in the established order on the basis of the received signal vector; calculates the Euclidean distance between the detected symbols and the symbol constellation points; determines values of the Logarithmic Likelihood Ratio (LLR) for estimating the soft output bit probability, and forms a group of the most probable candidate symbols from the points of the symbol constellation.
