Abstract

In this paper a very simple scheme is proposed which couples a maximum-likelihood sequence estimator with a N-element canceller. The method makes use of the MLSE's channel estimator to modify the locally generated training sequence used to obtain the antenna array weights. This method will increase the array's degree of freedom for interference cancellation by allowing the dispersive-desired signal to pass through the array undisturbed. Temporal equalization of the desired signal is then accomplished using maximum-likelihood sequence estimation. The T-spaced channel estimator coefficients and the array weights are obtained simultaneously using the minimum mean square error criteria. The result is a receiver structure capable of canceling N-1 in-band interference without compromising temporal equalization. The work in [1] is similar in concept as it beamforms towards all desired signal paths rather then canceling them.
