广义空间调制系统的低复杂度检测算法
A Low Complexity Detection Algorithm for Generalized Spatial Modulation Systems
摘要
Abstract
To overcome the disadvantage of high computational complexity of maximum likelihood( ML) de-tection algorithm for the generalized spatial modulation( GSM) system,a low complexity signal detection al-gorithm based on compressed sensing( CS) signal reconstruction theory is inverstigated. Firstly,under the channel model of multiple-input multiple-output( MIMO) ,through improving orthogonal matching pursuit ( OMP) algorithm,a candidate set of active antenna index is obtained. Then the ML detection algorithm is used to perform traversal search in the candidate set to obtain the active antenna index and the constellation modulation symbols. Simulation results show that the detection performance of the proposed algorithm is similar to that of ML detection algorithm and its computational complexity is about 2% of that of ML. Therefore,the proposed algorithm reduces the computational complexity while ensuring the detection per-formance,which achieves the favourable performance-complexity trade-off.关键词
