Abstract
A method for adaptively matching the frequency response of two channels of a received signal includes the steps of receiving a main RF signal on a main antenna, sampling the main RF signal at a sample rate, delaying the sampled main RF signal by a multiple of a sample period, wherein the sample period is the inverse of the sample rate, receiving at least one other RF signal on at least one other auxiliary antenna, sampling each of the at least one other RF signal at the sample rate, filtering each of the at least one other sampled RF signal utilizing an adaptive finite impulse response (FIR) filter having at least one sub-sample-period time delay, and combining the sampled main RF signal with each of the filtered at least one other sampled RF signals.
