An attractive feature of the Orthogonal Frequency Division Multiplexing (OFDM) system is its simple one-tap equalizer for linear channel distortions. Nevertheless, one still has to address the channel estimation issue. In mobile environments, self-recovery methods that avoid any recurring training overhead are of interest. In this paper, we propose a superimposed pilot scheme employing only a first-order statistic to identify the channel for OFDM systenis. It can be regarded as a semi-blind… CONTINUE READING
