Abstract

We introduce a subspace-based algorithm for the blind identification of time-dispersive channels in pulse shaping OFDM systems based on offset quadrature amplitude modulation (OFDM/OQAM). Our approach exploits cyclostationarity induced by the use of overlapping pulse shaping filters and uses second-order statistics only. The proposed method is similar in spirit to modulation-induced cyclostationarity. Our algorithm assumes symbol-rate sampling in the receiver and does not require knowledge of the channel order. We provide simulation results demonstrating the performance of the new method
