Abstract:
1. An adaptive antenna system, comprising: N antennae, wherein N is an integer greater than 1; N forward equalizers operatively coupled to a respective one of the N antennae; N processors performing a constant modulus algorithm (CMA) to thereby generate N respective control signals which adapt coefficients associated with each respective one of the forward equalizer a decision device receiving a signal based on the collected output of the N forward equalizers; and a feedback equalizer receiving an output of the decision device and generating a feedback signal biasing the signal received by the decision device, wherein a first control signal generated by one of said Nth processor adapts coefficients associated with the feedback equalizer and wherein a second control signal independent from the feedback equalizer is generated by a second processor among said N processors so as to adapt coefficients for a corresponding forward equalizer.
