Abstract
In this paper an investigative study has been made on the performance evaluation of encrypted text message transmission in 5G compatible multiuser frequency-domainsubband superposed FDSS scheme implemented MIMO OFDM wireless communication system The 2 2 multiantenna configured simulated system under consideration incorporates modern channel coding LDPC and Repeat and Accumulate RA and signal detection Cholesky decomposition based ZF detection Group Detection GD approach aided Efficient Zero-Forcing ZF and Lanczos method based efficient signal detection techniques In the scenario of transmitting encrypted text message over AWGN and Rayleigh fading channels it is noticeable that implementation of Repeat and Accumulate channel coding and Group Detection GD approach aided Efficient Zero- Forcing ZF signal detection techniques is very much robust and effective in retrieving transmitted text messages for all users
