**4. Conclusions and future work**

This article presents the advantages of single-user massive multiple input multiple output (SU-MMIMO) over multi-user (MU) MMIMO systems. The bit-error-rate (BER) performance of SU-MMIMO using serially concatenated turbo codes (SCTC) over uncorrelated channel is presented. A semi-analytic approach to estimating the BER of a turbo code is derived. A detailed signal-to-interference-plus-noise ratio analysis for SU-MMIMO over correlated channel is presented. The BER performance of SU-MMIMO with parallel concatenated turbo code (PCTC) over correlated channel is studied. Future work could involve estimating the MMIMO channel, since the present work assumes perfect knowledge of the channel.
