Python编程：从入门到实践

本文针对并行干扰抵消检测器的不足之处，提出了改进的并行干扰抵消检测算法——基于多项式展开的并行干扰抵消多用户检测算法。该算法将多项式展开检测器作为并行干扰抵消检测器第一级的数据估计值，以提高检测可靠性。通过仿真实验，首先验证了多项式展开检测器的性能。然后比较改进算法与传统检测器的性能，验证改进算法的系统性能得到明显改善；并与并行干扰抵消检测器、解相关检测器和MMSE检测器相比较，验 证得到该改进算法的性能也有不同程度的改善。 (this paper discusses the principle and performance of the conventional detector and the parallel interference cancellation(PIC)detector separately.Since the conventional detector take MAI only as the background noise without considering the existence of the other users,the existence of MAI has a significant impact on the performance of CDMA systems.Each stage of PIC detector utilizes the data estimates of the initial or previous stage,produces a new set of MAI estimates,and then subtracts out all of the MAI for each user in parallel.Through Monte Carlo simulation in different scenarios,the results illustrate the influence of MAI in conventional CDMA ystems.Theexperimental results show PIC detector can effectively eliminate MAI andimprove the system BER. )

说明：  对流层大气波导，可以使电波在较小的衰减下实现超视距传播，从而对无线电电子系统的运作产生严重的影响。对于通讯电路，它使系统间的相互干扰题目变得复杂；对于探测系统，产生的则是雷达空洞、超视距探测等题目。因此开展大气波导环境中电波传播特性及其应用的探究具有重大的理论意义和军事价值。 (Tropospheric waveguide, can make waves in the smaller attenuation achieve-the-horizon communication, and thus the operation of radio-electronic systems have a serious impact. For the communications circuits, which allows the mutual interference between systems has become a complex subject for the detection system is generated by the radar empty-the-horizon detection and other topics. Therefore, to carry out atmospheric environment of radio wave propagation characteristics of waveguides and its application to explore the theoretical significance and of great military value.)
