Research on MIMO Detection Algorithm
Abstract:Through the Multiple In Multiple Out (MIMO) technology, the capacity of wireless communication system and spectrum efficiency can be increased greatly without raising the bandwidth or power. This paper researches on several classical MIMO detection algorithms including ZF, ZF-SUC, ZF-OSUC, MMSE, MMSE-SUC and MMSE-OSUC. It discusses their advantages and disadvantages. Simulations are conducted to analyze their performance.
