## Abstract In this paper, a non‐data‐aided maximum a posteriori (MAP) channel estimation technique for OFDM systems employing M‐PSK modulation scheme is proposed. The technique requires a convenient representation of the discrete multipath fading channel based on the Karhunen‐Loeve orthogonal expa
