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

基于51单片机的GPS定位系统，在1602上显示经纬度等，通过开发板测试l啦啦啦啦啦啦啦啦！有能力的大神可以继续优化代码！

The idea behind differential GPS is to remove as much errors as possible from the range measurements by establishing these errors at a reference site. In its most simple setup, a GPS receiver is located at a well surveyed position and its (pseudo) range measurements are compared with the actual calculated range from this receiver to the SV s. The differences between measured ranges and calculated ranges at the reference receiver are applied as corrections to the ranges measured by other receiver(s) close by.

用Matlab将Radio Frequency（RF）收发模块进行模型化。非常少见用Matlab对RF的建模-Matlab will use Radio Frequency (RF) transceiver module model. Very rare with Matlab modeling of RF

描述DSCDMA多用户系统在AWGN信道下的误码率-Describes the DSCDMA multiuser system under error rate of the AWGN channel

GPS导航的源代码，vc源码，很实惠，希望下载-GPS navigation of source code, vc source code, it is affordable, I hope download

基于安卓的GPS定位开发源代码，java语言，解压之后直接导入就行了。

资源描述包含不能下到的这三个文件

然后再检查一下tcl，tck的版本号跟路径，如果不同的目录跟你自己的版本号换了版本号一样。

基于JT/T808 协议及数据格式的GPS终端模拟程序，符合交通部的例子，可以参考
