An SC-FDMA Channel Estimation Algorithm Research Based on Pilot Signals
SC-FDMA as LTE uplink main technology has been widely studied,at the same time,channel estimation around such technology is becoming hot,In order to research and increase channel estimation accuracy of LTE uplink system,an algorithm based on pilot is proposed in this paper,this algorithms main idea is,by setting a certain bit error rate,choosing some proper data after channel estimation done under R-LS and M-MMSE,combining the chosen data and former block pilot and increasing pilot number to do channel estimation again,system bit error rate and mean square error results can be got by simulation;at last,the theoretical analysis and simulation results show that this algorithm really can make the channel estimation accuracy improved and bit error rate decreased.
