This project demonstrates OFDM with adaptive modulation applied to Multiple-Input Multiple- Output (MIMO) systems. The analysis and simulation is considered in two stages. The rst stage involves the application of a variable-rate variable-power MQAM technique for a Single-Input Single-Output (SISO) OFDM system. The second stage applies adaptive modulation to a general MIMO system by making use of the Singular Value Decomposition to separate the MIMO channel into parallel subchannels.

In this paper, we present a Selected Mapping (SLM) PAPR reduction technique for MIMOOFDM system with special protection of Side Information (SI). Selected Mapping (SLM) is a powerful PAPR reduction technique since it does not cause any signal distortion and simple to implement. As a special protection for the Side Information (SI) of SLM technique, we propose a SI power allocation procedure. Simulation results show that our proposed technique gives significantly better BER performance than the ordinary SLM technique for MIMO-OFDM systems. Analysis for the optimum SI power allocation is also presented.
