Abstract
The present invention is directed to a multi-channel signal processing system that includes a fast Fourier transform (FFT) module configured to perform an FFT using a first channel time domain sample as the in-phase component of a complex signal input, and by using the second channel time domain sample as a quadrature component of the complex signal input. The FFT module provides a complex signal spectrum. A channel processing module is coupled to the FFT module. The channel processing module is configured to extract a channel sample spectrum as a function of the complex signal spectrum. A channel equalization module is coupled to the channel processing module. The channel equalization module is configured to multiply the channel sample spectrum by a channel reference spectrum to obtain a correlated and equalized channel sample spectrum.
