Carrier frequency offset (CFO) is one of the most important problems in an orthogonal frequency division multiplexing (OFDM) system, which seriously degrades the performance of the systems due to its time-variant behavior. This paper suggests a pilot-less residual CFO estimator for ultra-wideband OFDM (UWB-OFDM) systems. The proposed scheme uses a time… CONTINUE READING
