著名的GPS模糊度分解算法LAMBDA的matlab源程序 GPS软件开发必备

用matlab编辑的关于超宽带通信的BPSK调制的误码率分析,系统仿真时加入高斯白噪声,仿真结果给出了时域和频域图-BER analysis of the ultra wide bank BPSK communication channel with AWGN, time and spectrum figures are given in the end.

This a GPS communication source code to interrupt the NMEA code though serial port. Very good code to study and apply it to your own program.-This is a GPS communication source code to interrupt the NMEA code though serial port. Very good code to study and apply it to your own program.

这个程序是用来对PLLpre进行仿真的，该思想基于多方面的考虑-This procedure is used to PLLpre simulation, based on the thinking of a number of considerations

2410gps的测试代码，参考革新2410实验箱上的代码改写的！-2410gps test code, reference to innovative experimental box 2410 rewrite of the code!

本软件是专为《GPS应用程序设计》一书配套发行的。共分三部分：头文件、源程序和执行程序（包括配置文件和部分数据）-This software is designed for

此代码是仿真GPS L1 信号捕获。首先，它生成 CA 代码和相关的伪代码，然后乘以载波。然后，仿真信号的频谱被绘制。最后，频率偏移被加到了信号，本地通过与仿真信号的相关运算和使用已知的pn码来获得即时的起始代码和频率偏移量。

该程序是mobile５.0　ppc２００３系统下的，走http协议，通过无线网络的客户端升级程序．需要做在客户端升级的同仁们，可以参考一下．-The program is mobile5.0 ppc2003 systems and take the http protocol, through a wireless network client upgrade process. Does the client need to upgrade their Tongren, you can reference.

NGN－3G核心部件SGSN的代码实现，适合初学者学习，有详细的说明-NGN-3G core component code SGSN realize is suitable for beginners to learn, have a detailed description of

android gps jni源码函数调用了hw_get_module加载硬件适配模块.so文件，接着通过hw_device_t接口调用open()函数，实际执行了gps/loc_api/libloc_api/gps.c定义的open_gps函数，然后调用gps_device_t接口的get_gps_interface函数，此函数也是在gps.c中定义的，最后返回HAL层中loc_eng.cpp文件的sLocEngInterface，从而打通了上层到底层的通道。
