%X In order to study the channel estimation algorithms application for the transmit diversity mode in downlink TD-LTE systems,analyzed LS and RLS channel estimation algorithms based on discrete distribution cell-specific reference signals as the pilot. In order to simplify MIMO signal detection put two channel response correction methods forward for transmit diversity mode. The improved channel response correction method could track channel better using the time-frequency related properties. Through MATLAB simulation in Rayleigh fading channel, results show that the performance of RLS channel estimation is better than LS and the improved channel response RLS correction algorithm can further improve the performance of traditional correction algorithm.
