摘要

In this paper, the performance analysis of a (3 × 3) Multiple Input Multiple Output (MIMO) communication system is performed to achieve spatial diversity using linear minimum mean square estimation (LMMSE) decoding method at the receiver. We propose an efficient algorithm that achieves both spatial diversity and spatial multiplexing simultaneously. We called it parallel processing decoding technique. The proposed technique increases the rate of decoded symbol, improves the reliability of the transmission without employing STCs, and prevents any possible error propagation that may be presented in other sequential decoding methods. Simulation results demonstrate the advantages of using the proposed novel technique.
