说明：  数据通道剥离伪码后的载频估计,数据通道剥离伪码后的载波估计问题。对直接序列扩频系统的数据通道，假定接收设备已“完美”地锁定接收信号伪码，并实现了伪码剥离其中，信号幅度、电文、载波多普勒和载波相位均未知。电文的速率为10Hz。由于信源与接收端信号传输时延的不确定性，收到的信号电文是从某个未知时刻开始的。 利用数据文件 估计信号幅度、载波多普勒和载波相位(Data channel after stripping pseudo-code carrier frequency estimation)

永磁同步电机矢量控制程序，位置与角度判断可通过霍尔位置传感器，编码器得到，其中也含有无位置传感器程序(Permanent magnet synchronous motor vector control program, to determine the position and angle through the Hall position sensors, encoders get, which also contains the program without position sensors)

MIMO-OFDM的实现，不同点数的OFDM的实现以及SISO 和 MIMO之间的性能对比。(Implementation of MIMO-OFDM, OFDM, and the realization of the performance comparison of different points between SISO and MIMO.)

用矩阵撕裂法，多次用matlab运算，得出复杂系统的15个节点的电压(Tear voltage matrix method, repeatedly using matlab computing, complex systems derived 15 nodes)

中频70M，30M带宽LFM信号，采样率为102.4M，数字下变频后，还进行了三倍抽取，最后还得到I，Q两路信号 (IF 70M, 30M bandwidth LFM signal, the sampling rate of 102.4M, digital down conversion, the samples were carried out three times, the last also I, Q two-way signal)

自己编写的QPSK调制与解调，内含matlab-figure-file、matlab-M-file和得出的jpg格式图形！(I have written QPSK modulation and demodulation, containing matlab-figure-file, matlab-M-file and come to the jpg format graphics!)

电力系统故障计算，可以计算单相短路，单相接地短路，三相短路，两相短路接地，两相短路(power system fault, can calculate the single-phase short circuit, short-circuit to the single-phase and three-phase short-circuit, two-phase short-circuit grounding, two phase short circuit)
