This paper proposes low-complexity time-domain channel estimators for OFDM systems. Time-domain channel estimation combined with frequency domain equalization is an attractive approach, since it can provide lower complexity and better estimator performance than pure frequency domain processing. In the particular case of constant modulus (M-PSK) modulation, we show that the transmission matrix is unitary. Therefore, the simple correlator channel estimator turns out to be optimal. For the case of… CONTINUE READING
