In this paper, incorporates a comprehensive BER simulation study undertaken on the effectiveness of a multi-user Multiple Input and Multiple Output (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.
