This paper incorporates a comprehensive BER simulation study undertaken on the effectiveness of a multi-user MIMO OFDMA wireless communication system on encrypted data transmission. The channel encoded and spatially multiplexed multi-user MIMO OFDMA system under investigation implements Pre-RSNA cryptographic algorithm. The simulated system deploys three linear signal detection schemes (Equalizers) such as Minimum Mean Square Error (MMSE), Zero Forcing (ZF) and Q-Less QR decomposition under BPSK, DPSK, QPSK and QAM digital modulations. It is anticipated from computer simulation tests with synthetic data transmission that the multi antenna supported OFDMA wireless communication system outperforms in Zero Forcing (ZF) channel equalization scheme with BPSK digital modulation and shows comparatively worst performance in Q-Less QR channel equalization scheme.
