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.

车载自组织网络中路边性能及防碰撞算法研究1-9
说明： 在车载网络中，尤其是在城市环境下，车辆高速移动导致网络拓扑结构频繁变化，车辆密度分布不均，导致稀疏连通和局部最优情况频繁出现，所以必须专门为车载自组网设计具备鲁棒性、可靠性、实时性的路由协议。本章针对现有城市环境下存在的车辆碰撞问题，利用车辆的地理位置和电子导航地图提供的道路车流信息进行路由决策，根据设定的城市交通网络模拟图，随机的分布车辆节点，通过十字交叉路口的防碰撞研究以及路边节点之间的相对位置预警仿真，得到不同仿真下的城市交通信息网络结果图，对于该区域交通通信设计以及路况信息改善有一定的指导意义(In the vehicular network, especially in the urban environment, the high-speed movement of vehicles leads to frequent changes in network topology and uneven distribution of vehicle density, which leads to the frequent occurrence of sparse connectivity and local optimization. Therefore, it is necessary to design a routing protocol with robustness, reliability and real-time for vehicular ad hoc networks. Aiming at the problem of vehicle collision in the existing urban environment, this chapter uses the geographic location of the vehicle and the road traffic flow information provided by the electronic navigation map to make routing decisions. According to the set urban traffic network simulation diagram, the vehicle nodes are randomly distributed.)
