【摘要】 为了充分利用多输入多输出(MIMO)的高信道容量和连续相位调制(CPM)的高频率利用率优势,同时有效降低MIMO-CPM系统的接收译码复杂度,提出了利用正交空时编码(OSTC)方阵变换实现、适用于MIMO-CPM的符号发送方阵和辅助数据矩阵的设计方法,并通过辅助数据矩阵设计方法将正交空时编码推广应用于全响应CPM的任意发送天线系统,将接收译码复杂度由符号电平数M的n次方降低为Mn的线性关系.仿真数据表明,采用该辅助数据矩阵实现的MIMO-CPM正交设计,分集增益仍服从秩准则.更多还原

【Abstract】 A method was proposed to design a signal matrix and data-aided matrix derived from the square-matrix of orthogonal space time coder(OSTC) for multiple input multiple output-continue phase modulation(MIMO-CPM) in order to fully use the high capability of MIMO channel and the high frequency efficient of CPM and evidently reduce the complexity of MIMO-CPM decoder.The method expanded the space time coder for full response CPM to arbitrary antenna of transmitter with the design of data-aided matrix.Then the complexity of receiver was reduced from Mn to nM where M is the multiple level of signal.The simulation results show that the diversity gain accords with the order of rank rules.更多还原
