Abstract
A receiver may comprise a plurality of signal processing paths, a bin-wise combiner, and an inverse transformation block. Each signal processing path may comprise a transformation block that is operable to transform a time-domain digital signal to an associated frequency-domain signal having a plurality of subband signals. The bin-wise combiner may be operable to combine corresponding subband signals of the plurality of signal processing paths. The inverse transformation block may be operable to transform output of the bin-wise combiner to an associated time-domain signal. The transformation block in each said signal processing path may be a Fast Fourier Transform (FFT) block. The number of points used by the FFT block of any one of said plurality of signal processing paths may be based on the delay spread of a signal input to the one of the signal processing paths.
