感应电机终端滑模矢量控制系统,simulink仿真实验程序。(Induction motor vector control system of the terminal sliding mode)

说明：  matlab实现的GPS软件接收机，CA码生成，导航电文，捕获、跟踪(software gps receiver)

使用多路径信道进行数据的传输仿真（架设在已知信道中传输）(Data transmission using the multi-path channel simulation (mounted on a known channel transmission))

对GPS和DR组合导航的数据进行卡尔曼滤波处理(The GPS and DR integrated navigation Kalman filter data processing)

典型宽带信号处理方法，频率聚焦技术csm，宽带信号频率范围100-3100hz，对远场两个宽带信号源进行定位。(A typical broadband signal processing methods, frequency Focusing csm, broadband signal frequency range 100-3100hz, two pairs of far-field wideband signal source location.)

说明：  Zigzag和iZigzag的程序及改进的Zigzag和iZigzag的程序。后者可以大幅提高运算效率(Zigzag and iZigzag procedures and improved Zigzag and iZigzag procedures. The latter can substantially increase the computing efficiency)

结合QPSK调制的直接序列扩频系统的仿真(Combined with QPSK modulation direct-sequence spread-spectrum system simulation)

采用BPSK调制技术，用ZF和ZF加并行干扰消除的方法检测系统的误码率。(Using BPSK modulation technique, with the ZF and ZF plus parallel interference cancellation method to detect the BER.)

说明：  通过广播星历自动计算某卫星一天内各时刻的位置，并和同目录精密星历比对精度。注释很多。(The position of each time in a day is calculated automatically by broadcast ephemeris, and the accuracy is compared with that of precise ephemeris in the same catalog. There are many comments.)
