哈尔滨工程大学word格式论文，基于差分演进算法的TDOA定位技术。提出了三种新的定位算法：基于TDOA的Chan-GA算法、Chan-DE算法和Chan-IDE算法。并在相同的仿真环境下进行比较，仿真结果表明，在保证种群数量的情况下，所提的算法性能稳定，能找到逼近全局最优点的解，相对于Chan算法精度更高,相对于以前的算法在保证收敛性能的前提下有更快的收敛速度。(Harbin Engineering University, word format papers, based on differential evolution algorithm TDOA positioning technology. Proposed three new localization algorithm: Based on TDOA Chan-GA algorithm, Chan-DE algorithm and Chan-IDE algorithms. And in the same simulation environment to compare simulation results show that, in the case of populations to ensure that the proposed algorithm performance and stability, can be found close to the global optimal solution, Chan algorithm with respect to higher accuracy compared to the previous algorithm convergence performance guarantee under the premise of a faster convergence.)

在Microsoft Visual C++软件环境下，用C++ 语言实现整个仿真。将整个产生系统分为C/A码产生，信号产生，量化三个模块，经过编写和调制实现产生的基本功能，即输入导航电文及控制数据，例如 选取卫星信号，多 普勒频移，采样周期。最后可以得到加入服从高斯分布的噪声信号的数字离散中频信号。 (We use the C++ language to archive the simulation in the Microsoft Visual C++ circumstance. The entire generating system is divided into three parts,including C/A Code, Signal Generating and Quantizer. After writing codes and checking and confirming, I archive the basic functions. If you input the guiding codes and controldata like satellite selecting signal, Doppler frequency movement, sampling period, at last you can get the digital middle frequency signals with gauss distributing noise)
