摘要：

Orthogonal frequency-division multiplexing (OFDM) combines the advantages of high performance and relatively low implementation complexity. However, for reliable coherent detection of the input signal, the OFDM receiver needs accurate channel information. The Doppler shift of fast-fading channels will generate intercarrier interference (ICI) and, hence, degrade the performance of orthogonal frequency division multiplexing (OFDM) systems. In this paper, the ICI is considered disturbance of channel information.We present total least-squares (TLS) scheme to eliminate the ICI and noise.
