摘要
A novel least-squares (LSs) channel estimation method for OFDM systems is proposed. Compared with the conventional LS method, the proposed method employs several extra steps to suppress the noise effect. Thus, it can provide a better estimation performance than the conventional LS method. Moreover, the proposed method does not increase the occupation of frequency-band resources and has some application value for engineering. Simulation results demonstrate the performance of this method.
