在直角的频率部门 multiplexing (OFDM ) ,系统,一时间和频率领域最不意味着方形的算法(TF-LMS ) 被建议取消频率偏移量(FO ) 。TF-LMS 算法由二个阶段组成。第一,预定领域最不吝啬的平方(TD-LMS ) 计划被选择到预先取消在时间领域的频率偏移量,然后剩余频率偏移量导致的干扰被频率领域平均数平方(FD-LMS ) 消除在频率领域的计划。星座考虑的小点错误率(BER ) 和调音的照阶段移动(QPSK ) 的结果证明建议抑制算法的表演是优秀的。
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.
