Abstract

For burst mode in slowly time-varying channel, channel state information can be obtained mostly based on preamble and supposed maintain constant. 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.
