简介：我们由分析推理和随机的模拟在一个单个阀值的传感器系统在随机的回声上调查alpha马厩噪音的效果。随机的回声在alpha马厩噪音环境发生在阀值系统，这被显示出，但是反响的效果变得作为alpha马厩索引减少或alpha马厩分发增加的偏斜度参数变弱。特别地，为Cauchy噪音，在最佳的噪音偏差参数，信号振幅和阀值之中的一种非线性的关系是为输出signal-to-noise比率使用极端值条件获得并且说明的经分解。在这通讯介绍的结果应该在non-Gaussian在信号察觉和图象恢复有申请吵闹的环境。

简介：为了加快全球定位系统（GPS）的捕获速度，提高系统的捕获灵敏度，对GPS系统捕获策略进行了深入地研究。在对其捕获的基本原理和传统的最大值捕获系统进行分析的基础上，提出了一种新颖的GPS多峰值捕获策略。该策略通过多峰值选择减少了系统搜索单元数目，通过增加进入唐检测器的峰值个数来提高捕获灵敏度。利用蒙特卡洛方法进行了仿真分析，仿真结果表明：该新颖策略的捕获时间更短，同时捕获灵敏度比传统的最大值捕获系统要高2.8dB。总体来说，该新颖策略算法更适用于对GPS弱信号的捕获，也可应用于其他卫星导航系统。
