Outline of Final Research Achievements

Spatial multiplexing based on large-scale MIMO systems has been considered as a promising approach for future broadband wireless systems, but the optimal detection of multiplexed symbols is challenging due to its extremely high computational complexity. Therefore, its feasibility depends on the development of low-complexity algorithms for symbol detection. In this work, we have developed (1) a new symbol detection algorithm based on extension of parallel candidate adding approach for coded MIMO systems, and (2) a new modified algorithm based on symbol distribution approximation that enhances the symbol detection performance without significant increase of computational complexity at the receiver.
