正交空间调制系统的低复杂度检测算法
A low complexity signal detector in quadrature spatial modulation system
摘要
Abstract
QSM (quadrature spatial modulation) has been paid much attention recently to an extended spatial modulation transmission scheme which improves the spectral efficiency by independently transmitting the real and imaginary parts of a complex data symbol.ML (maximum likelihood) detector for QSM system has to exhaustively search in the whole search space,so the complexity of ML detector is very high.For the high complexity of QSM system detection,a low complexity detector based on the concept of CS (compressed sensing) is proposed by exploiting the fixed sparse property of quadrature spatial modulation system signals.The simulation results show that the novel detector exhibits near-maximum likelihood detector bit error performance and its complexity is about 4.7％ of ML.关键词
