实现信号处理中QAM调制、过信道、解调部分。其中QAM调制部分可改符号点数，M阶数，信道加高斯白噪声、时延、多径，调制解调均有星座图。通过本代码，可学习QAM调制解调，或者通信系统的知识。(To achieve QAM modulation, signal processing over channel, a demodulation section. QAM modulation section can be changed symbolic points M order channel additive white Gaussian noise, delay, multipath, the modem has constellation diagram. QAM modulation and demodulation, or communication system knowledge through this code, you can learn.)

MATLAB代码，完整实现GPS L1CA信号的从捕获、跟踪到定位的全部过程。代码鲁棒性好，有注释，适合学习，也可直接使用(The MATLAB code fully realizes the whole process of GPS L1CA signal acquisition, tracking and positioning. Code is robust, annotated, suitable for learning, and can be used directly.)

说明：  本资料是关于dsplib的使用说明，其中还包括了各种算法的源码(This information is for use on the dsplib, including the source of various algorithms)

西电DSP实验课程大作业和程序另一种写法，包含MATLAB和DSP程序，可以直接仿真实现(Great Western Power DSP experimental program and procedures for another writing job, including MATLAB and DSP programs can be directly Simulation)

该源码讲解了DSP2812的中断使用方法。(The source explained the DSP2812 interrupt use.)

说明：  永磁同步电机PMSM用2812编写的一段程序，代码是C，有详细注释(Permanent magnet synchronous motor PMSM using a program written in 2812, the code is C, with detailed notes)

svc的仿真图形，用以证明其工作原理的正确性(svc simulation graphics to prove the correctness of their works)

GPS仿真MATLAB软件，可以进行坐标转换，伪距求解，误差分析等(Calc_Azimuth_Elevation；Distance；ECEF2GPS；Error_Ionospheric_Klobuchar；Error_Satellite_Clock_Offset；Error_Tropospheric_Hopfield)

说明：  一些DSP编程的例程 挺有帮助的 大家看看吧(A number of DSP programming routines quite helpful to everyone to see it)
