Abstract :
Recently, multiple-input multiple-output (MIMO) technology has emerged as a new paradigm of highly spectrum-efficient wireless communications. This paper describes a MIMO system, and presents variable-power variable-rate MQAM modulation in MIMO systems. The proposed rate quantization algorithm is described, followed by the simulation results and a brief conclusion.
