- W2545360908 abstract "Orthogonal Frequency Division Multiplexing (OFDM) is multiplexing technology of orthogonal multi-carrier, and the channel estimation model based on pilot in OFDM systems is analyzed; Now that, the channel estimation based on pilot needs interpolation, in order to reduce the complexity of the interpolation algorithm, the FFT channel estimation algorithm based on pilot is studied. Because of the direct FFT channel estimation algorithm existing energy spectrum leakage problems, the optimized FFT channel estimation algorithm based on the Hamming windowed function is put forward. The simulation results show that in the multi-path fading channel, the proposed algorithm can effectively improve performance of channel estimation in OFDM systems." @default.
