Integrated multielement receiver structures for spatially distributed interference channels

The structure and performance of a maximum likelihood (ML) receiver for reception in spatially distributed interference channels when a multielement array capability is available are described. Under the assumption of Gaussian interference, the receiver consists of an optimum ML array processor followed by a sequence estimator implemented using the Viterbi Algorithm. Numerical results are provided to illustrate the symbol error probability performance of this optimum ML receiver. A completely adaptive realization of this scheme is described with performance illustrated through simulation.
