Cooperative spectrum sensing for cognitive radios using jointly adaptive FRESH filters

Abstract: In this paper, the problem of cooperative spectrum sensing of cyclostationary signals for cognitive radios is considered. It has been shown that the MMSE optimal filters for cyclostationary signals involve one or more frequency shift branches and are called FRESH (FREquency SHift) filters. Adaptive FRESH filters have been used in the past to enhance cyclostationary signals so as to ease their detection in AWGN channels. It has been observed that space time FRESH filtering leads to gains of up to 10 dB over a s… Show more

“…Most man‐made signals prefer a cyclostationary (CS) model rather than a stationary one, or equivalently, they exhibit spectral correlation , that is correlation between time‐shifted and frequency‐shifted versions of themselves, with the frequency shifts related to their hidden periodicities [1]. In the last decade, beneficial characteristics of signal cyclostationarity have received much attention, and have been intensively exploited in varied domains including signal parameter estimation [2–5], interference suppression or signal separation[1, 6–8], array beamforming [9–12] and recently, spectrum sensing [13–16].…”
