In this paper, a comprehensive study has been made to evaluate the performance of a Single Carrier Frequency Division Multiple Access (SC-FDMA) based wireless communication system. The 2-by-2 spatially multiplexed Turbo encoded SC-FDMA system under investigation incorporates Quasi-orthogonal space-time block coding (Q-STBC) scheme and three linear signal detection techniques (Equalizers) such as Minimum Mean Square Error (MMSE), Zero Forcing (ZF) and Q-less QR Decomposition under BPSK, DPSK, QPSK, DQPSK and QAM digital modulations. In the present simulated system, data transmission has been secured with implemented ECB cryptographic algorithm. It is noticeable from simulation results that a significant improvement of system performance is achieved with the Q-less QR Decomposition based signal detection scheme under QAM digital modulation technique. The results also clarify that the system performance deteriorates with increase in order of digital modulation and noise power as compared to signal power.
