《gps基本原理及其matlab仿真》(西安电子科技大学)里面的程序源代码，都是自己亲自敲上的。对入门很有用的。这是获取导航信息的。(The basic principle of GPS and the matlab simulation (xi an university of electronic science and technology) in the program source code, is knock on yourself. The introduction is very useful. This is for navigation information. )

说明：  The elegant and special HW for signal processing, GSD part

在ADI公司dsp芯片sharc21489中通过DMA实现延时功能，配合sigma for sharc使用,输入有两个参数，一个是延时时间，另一个是延时需要放在片外那个地址。(In sharc21489 delay by the DMA function, with sigma for sharc use, there are two input parameters, a delay time, and the other is the delay needs to be placed chip that address)

Gardner位同步算法与锁相环的联合仿真程序.加入了时偏和频偏，能很好地锁定时偏和频偏，得到最佳采样输出。(Gardner bit synchronization algorithm and phase-locked loop joint simulation program, adding time offset and frequency offset, can well lock the bias and frequency offset, get the best sampling output.)
