一种新的空间调制QPSK信号检测算法
A new algorithm for spatial modulation QPSK signal detection
摘要
Abstract
Spatial modulation (SM ) is a novel multi-antenna transmission scheme which jointly uses active antenna indices and conventional signal set to convey information . Since the maximum likelihood (ML) optimal detection algorithm for SM systems needs to detect both the active antenna index and the transmitted signal ,the detection complexity is very high .To solve this problem ,based on the global optimal conditions of a binary quadratic programming a novel optimal ML simplified algorithm for SM QPSK signal is proposed . On the premise of having the same ML-optimal performance with the conventional ML-detector , the computational complexity of the proposed detector has been significantly reduced , especially in large antennas SM system . Finally , the simulation results are presented to show the M L-optimal performance of the proposed detector .关键词
