一种低复杂度的MIMO迭代检测算法
Low complexity MIMO iterative detection algorithm
摘要
Abstract
In order to reduce complexity of the joint detection algorithm in MIMO system and to guarantee performance of the system, this paper proposed the FP-MAP algorithm, which used the soft information during the searching process of sphere decoding. The algorithm in calculating the maximum likelihood information used its soft priori information, and obtained the soft extrinsic information in the iterative process. Theoretical analysis and simulation shows that, compared with the LSD-MAP algorithm , FP-MAP algorithm has relatively lower complexity, but the BER performance of FP-MAP algorithm is equal to the LSD-MAP algorithm,compared with the SIC-MMSE algorithm, the performance FP-MAP algorithm is superior to SIC-MMSE algorithm.关键词
