RS码的FPGA实现，verilog语言形式，好参考资料(FPGA realization of RS code, verilog language form, a good reference)

说明：  实现GPS信号的无码捕获及多普勒频移获取(Acquisition of GPS Signal and Doppler Frequency Shift)

generate sine wave. Inputs : Amplitude, phasein, frequency

利用C语言进行GPS网平差的程序设计。包含求逆，矩阵乘积，转置，平差等运算。(failed to translate)

GPS软件接收机的源码，实现信号跟踪、捕获、电文解调、定位解算等功能，有助于学习卫星导航的同学加深对GPS接收机工作原理的理解，也可作为核心代码扩展为GPS接收机工作原理演示程序。(The source code of the software GPS receiver signal tracking, capture, message demodulation, position resolution and other functions, help students to learn satellite navigation to deepen understanding of the GPS receiver works can also be extended as the core code for the GPS receiverworking principle of demo program.)

说明：  acousting fingerprint enhancement

说明：  这个程序能很智能地计算贴片天线的各个参数，只要给出其中的任意参数就能计算出其他(This process can be very smart to calculate the various parameters of patch antenna, as long as give them any other parameters can be calculated)

点亮led流水灯，通过调用锁相环，可以更改对应的时钟。(Lighting the LED pipelining lamp, the corresponding clock can be changed by calling the phase-locked loop.)
