Abstract
A system is described for performing combined equalization. The system comprises a time domain equalizer (TEQ) configured to receive a signal and shorten a CIR (channel impulse response) of the received signal, a Fast Fourier Transform (FFT) module for demodulating the received signal, and an equalization block for reducing inter-carrier interference (ICI) and inter-symbol interference (ISI). The equalization block comprises at least one of: a feed forward equalizer and a feed back equalizer. The system further comprises a slicer circuit configured to generate a hard-limited decision for a symbol corresponding to the received signal.
