In view of expense of extra redundancy and reduced spectral efficiency, prefix based multicarrier transmission can find its major applications in 5G and beyond 5G wireless communication networks with properly designed low complexity signal detection technique. Hybrid prefixing aided multicarrier modulated system is capable of providing reasonably acceptable bit-error rate (BER). In this paper, a comprehensive study has been made on performance evaluation of hybrid prefixing scheme implemented multicarrier cmWave wireless communication system on transmission of encrypted audio signal in a hostile flat fading channel. The 4×4 multi antenna configured simulated system under investigation incorporates LDPC and Repeat and Accumulate channel coding and various types of digital modulations (16-PSK, 16-DPSK, and 16-QAM) and signal detection (MMSE, and Cholesky Decomposition based) techniques. The implementation of pulse shaping filter in the simulated system is very much convenient to improve system performance in terms of BER through reduction of intersymbol interference (ISI). Additionally, utilization of hybrid prefix scheme enhances spectrum efficiency of the simulated system. It is noticeable from MATLAB based simulation study that the Repeat and Accumulate channel encoded simulated system is very much robust and effective in retrieving audio signal under utilization of Cholesky Decomposition based signal detection and 16-QAM digital modulation techniques.
