On the bit error rate analysis of M-PSK systems using LMMSE channel estimation and MRC/EGC diversity combining over Ricean-Fading channels

摘要

In this paper, Bit Error Rate (BER) performance analyses of the pilot symbol-aided modulation (PSAM) for M-PSK (M-ary Phase Shift Keying) system with Linear Minimum Mean Square Error (LMMSE) channel estimation technique that exploits the maximal-ratio combining (MRC) and equal-gain combining (EGC) schemes are performed for different antenna diversity combining schemes and modulation levels, over Ricean fading channel. Increasing the antenna diversity at the receiver provides lower BER at the same Signal-to-Noise Ratio (SNR). As it is analyzed in the simulation results the M-PSK modulated MRC technique has a better performance than the EGC technique.
