| Abstract: | In this paper,a joint channel estimation scheme based on least square(LS) method for orthogonal frequency division multiplexing(OFDM) system is proposed,which is also optimized in theory.The simulation results show that the new method can not only enhance the estimation accuracy,but also reduce the importance of the pilot power. |
