摘要
An improved multi-antenna receiver is realized for detecting signals transmitted by a multi-antenna transmitter by summing signals received at the plurality of receiver antennas after multiplying each by a respective constant. The summed signal is applied to a maximum likelihood detector. The respective constants, lambda j, where j is an index designating a particular receiver antenna, are determined by evaluating the largest eigenvalue of the matrix LAMBDA A( LAMBDA *)T, where LAMBDA is a vector containing the values lambda j, and A is a matrix containing elements alpha ij, which is the transfer function between the ith transmitter antenna to the jth receiver antenna. The alpha ij terms are determined in the receiver in conventional ways. IMAGE
