Abstract：OFDM (Orthogonal Frequency Division Multiplexing) is being widely used in the next generation of wireless communication systems as an efficient transmission technology .In this paper ,a low complexity LS (least squares) channel estimation algorithm which inserting comb pilot data in the frequency domain is proposed in OFDM system .Simulation re‐sults prove the superiority of the algorithm in Rayleigh multipath fading channel .Meanwhile ,the simulation results also show that the superiority of this algorithm will become no longer significant when the channel changes too fast .
Keywords：OFDMleast squarechannel estimate
