摘要 In an orthogonal frequency division multiplexing(OFDM) system,a time and frequency domain least mean square algorithm(TF-LMS) was proposed to cancel the frequency offset(FO).TF-LMS algorithm is composed of two stages.Firstly,time domain least mean square(TD-LMS) scheme was selected to pre-cancel the frequency offset in the time domain,and then the interference induced by residual frequency offset was eliminated by the frequency domain mean square(FD-LMS) scheme in frequency domain.The results of bit error rate(BER) and quadrature phase shift keying(QPSK) constellation figures show that the performance of the proposed suppression algorithm is excellent. In an orthogonal frequency division multiplexing （OFDM） system, a time and frequency domain least mean square algorithm （TF-LMS） was proposed to cancel the frequency offset （FO）. TF-LMS algorithm is composed of two stages. Firstly, time domain least mean square （TD-LMS） scheme was selected to pre-cancel the frequency offset in the time domain, and then the interference induced by residual frequency offset was eliminated by the frequency domain mean square （FD-LMS） scheme in frequency domain. The results of bit error rate （BER） and quadrature phase shift keying （QPSK） constellation figures show that the performance of the proposed suppression algorithm is excellent.
