Abstract
- Multiple users are served simultaneously in MIMO system, it potentially triggers an MUI. Precoding schemes are developed to suppress interference. By suppressing the interference that means it is increasing the performance of MIMI system in term of BER, sum rate and CDF. This work compares three precoding schemes including MMSE TH, MMSE BD, and ZF BD. Based on numerical results, the MMSE TH outperforms than the MMSE BD and ZF BD precoding schemes. At specific BER 10-3, The MMSE TH requires 6.6 dB of SNR, it is the lowest value than the MMSE BD and ZF BD. In addition, maximum CDF (probability sum-rate is 100 %) of the MMSE TH is reached at 6 bps/Hz, the MMSE BD is 4 bps/Hz and the ZF BD is 3 bps/Hz, respectively. Although, the MMSE TH precoding has higher computational complexity but it can suppress effectively the MUI thus increasing the performance of MU MIMO system. [ABSTRACT FROM AUTHOR]
