Pilot Contamination Reduction
应用背景This paper considers the problem of interference mitigation in multi-cell multi-antenna time division duplex (TDD) wireless systems for downlink transmission. An efficient way to obtain channel state information (CSI) at the base station is by using uplink pilots and reciprocity of the downlink channel.
At the same time, it has been shown that pilots from different cells contaminate each other, resulting in corruption of precoding matrices used by base stations, and high inter-cell interference. This paper studies the effects of shifting the location of pilots in time frames used in neighboring cells, and its effectiveness in obtaining better channel estimates, and, thereby, inter-cell
interference reduction.关键技术Wireless cellular network designs with multiple antennas have been adopted by several modern wireless systems, which aim for high throughput as well as high

多目标Pareto最优解搜索算法
多目标优化是指在约束条件下有两个或两个以上的优化目标,而且这些目标之间相互矛盾,不能同时达到最优,也就是说,一个目标的最优往往是以牺牲其它目标作为代价的,因此多目标优化问题存在多个最优解,这些解之间无法比较优劣,统称为Pareto最优解。带精英策略的快速非支配排序遗传算法(Nondominated Sorting Genetic Algorithm II,NSGA-II)是目前应用较为广泛的一种多目标算法。本案例将对MATLAB自带的改进的NSGA-II进行讲解,并举例说明其应用。
