单片机发送报文控制手机模块GR47进行gprs连接登陆，发送接收数据(SCM reportedly sent mobile phone text control module for EDGE connectivity GR47 landing, send and receive data)

DS-CDMA链路中加入基于子空间的PASTd多用户检测方法。系统中采用m序列阔频，可以通过高斯信道或瑞利信道。可以直接运行得到不同信噪比下的误码率曲线。(DS-CDMA link added Subspace-based multiuser detector PASTd. M sequence used in the system wide-band, Gaussian channel, or by Rayleigh channel. Get different signal to noise ratio can be run directly under the BER curves.)

说明：  OFDM信号的循环谱密度，非常详细，根据协议编的，外面非常少见！(OFDM signals in cyclic spectrum density, very detailed, made under the agreement, the outside is very rare!)

MIMO系统线性均衡，ZF均衡，MMSE均衡，及其改进算法(MIMO system linear equalization, ZF equalization, MMSE equalization, and its improved algorithm)

针对盲模拟调制信号的自动识别算法，利用了盲信号识别中常用的gamma、ap、dp、P等参数，并附送dsb、lsb、usb、am、fm信号的生成程序(Automatic analogue modulation recognition using MATLAB. There is also a function to generate dsb,lsb,usb,am,fm signal)

说明：  实现了lfm信号的仿真，可以对其频谱和时域波形进行分析，并且仿真了其模糊函数，可以分析其雷达性能。(The simulation of LFM signal is realized, and its spectrum and time domain waveform can be analyzed, and its ambiguity function can be simulated to analyze its radar performance.)
