Application of GA & PSO Based Algorithm in MIMO Detection

Abstract

LTE system consist of MIMO-OFDM technology which have been widely used for high speed communication in 4G & 5G. A difficulty encountered in design of MIMO Receiver in detecting of signal in noisy & large MIMO environment of the transmitted signal. To get minimum error of probability designing of a receiver is required by considering theoretical & practical difficulties. However, with this design receiver will become more complex. MLD &VBLAST is the optimal method for signal detection but with increase in modulation order & transmit antenna amount complexity increases. This paper shows that GA & PSO algorithm will reduce computational complexity & will increase convergence speed & will detect signal of LTE it will give near optimal bit error rate.
