Adaptive antenna array using a combined coherent and constant modulus reference signal

摘要

An apparatus for performance improvement of a digital wireless receiver comprises a processing circuit for processing a plurality of received signals and providing a processed signal, wherein each of the plurality of received signals is weighted and combined to provide the processed signal; and a generation circuit for computing a composite reference signal for use in weight generation. The composite reference signal is computed as a weighted average of a coherent reference signal value and a constant-modulus reference signal value.
