LTE_Simulator
LTE的系统级仿真平台的搭建，包含每个模块，以及每个模块如何使用，都有介绍，里面还包含两个pdf文档(LTE System Level Simulator Documentation,This document contains documentation on how to use the Long Term Evolution (LTE) System Level simulator [1] as well
as some insight on its structure and the assumptions that were made while developing it. This document relates more on how to
actually use the simulator. The concept and the structure of the simulator is described in more detail in [2])

把地理区域分成一个个小区，蜂窝系统在该区域内提供无线覆盖。把可用的频谱分成很多信道，每个小区分配一组信道。使用频分双工（FDD）。在小区间进行频率利用，N个小区构成一个簇，簇间进行频率复用。定义了传播特性（信道参数）以及同频小区的位置。信道的参数包括：小区半径，路径损耗指数，以分贝为单位的对数正态阴影的标准差，基站发射功率级，移动台发射功率级，每个小区的扇区数，扇区化天线的正反向比，要仿真的瞬时位置的组数，同频干扰阈值。(To a geographical area is divided into small areas, cellular systems in the region to provide wireless coverage. The available spectrum is divided into multi-channel, each plot the distribution of a group of channels. The use of frequency division duplex (FDD). In the district between the frequency of use, N plots constitute a cluster, cluster between frequency reuse. The definition of the propagation characteristics (channel parameters), as well as with the frequency of residential location. Channel parameters include: cell radius, path loss index to decibels for units Lognormal shadow of the standard deviation, the base station transmitter power level, mobile station transmitting power level, the number of sectors in each district, sector of the antenna the pros and cons to the ratio, to the transient simulation of the group a few positions, the same frequency interference threshold.)

Trackdemo
说明： 用于对基于GOLD码的串行捕获算法，可以自定义信噪比，待捕获信号参数，代码分成搜索跟踪和捕获两部分，其中搜索的步长等参数也可以自定义，代码中acquiresignal.m部分为最终捕获相位展示的主程序。(For the serial acquisition algorithm based on GOLD code, we can customize the signal-to-noise ratio and the parameters of the signal to be captured. The code is divided into search part and capture part, The parameters such as search step can also be customized. Acquiresignal.m part is the main progress to output the results of the capture of phase.)
