In fact,for different OFDM symbol,channel change slowly,so the assumption degrades the system performance. A low-complexity technique is presented to estimate and track the channel for ZP-OFDM. Channel state information can be obtained in the first OFDM symbol based on comb-type pilots and tracked by insert a bit in time-domain for others OFDM symbols. Simulation results verify the improved performance of the proposed method. %K OFDM %K Burst mode %K Channel estimation
