摘要
联合空时分层码,提出了一种CPM信号Laurent分解和最小均方误差检测相结合的低复杂度接收机,在降低运算量的同时,保证了低信噪比情况下接近于最大似然ML、最优检测器的接收机性能。理论推导和仿真结果均验证了该算法的有效性。
Increasing attention is paid to Continuous Phase Modulation （CPM） system due to its characteristics of constant amplitude and high spectrum effectiveness in the field of wireless communication,so reducing the decoding complexity of the system is a key topic.In this paper,based on Layered Space Time （LST）,a receiver of reduced complexity consisting of Laurent decomposition of CPM signals and MMSE detector is presented.In the low SNR condition,it achieves near-Maximum Likelihood （ML） performance with feasible complexity.Both theoretical derivation and simulated result confirm the effectiveness of the proposed method.
