In this paper, the authors made simulative study on secure data transmission in a multi-group space time encoded OFDM-TDMA wireless communication system. The system under investigation implements a modern hybrid concatenated channel encoder; four signal detectors such as ZF, MMSE, lattice reduction-aided MMSE and BLUE based signal detection under QAM, QPSK and DQPSK digital modulations. Based on the simulation result with Matlab, it is inferential that the simulated system is highly robust in retrieving transmitted data under Rayleigh fading channel in QAM digital modulation and lattice-reduction-aided MMSE signal detection scheme.
