A device and method for receiving and processing single carrier and multiple carrier signals through substantially common elements within a receiver that uses a radix 2 FFT on the signal, equalizes both types of signals in the frequency domain and then, for the multiple carrier signal performs a polynomial interpolation to bring the signal to symbol rate and for the single carrier signal performs an IFFT and samples the output to produce a signal at symbol rate.

Unified single and multiple carrier receiver architecture

A signal receiver inputs a signal, computes a set of equalizer tap values during a signal acquisition phase by applying an algorithm iteratively to a given set of training data contained within the signal, and uses the set of equalizer tap values to perform signal equalization during the signal acquisition phase. The algorithm includes computing and applying phase correction to the pre-equalized signal at each adaptation step to correct for phase error related to the main path only, of the input signal.
