移动通信中的智能天线系统源代码,波束面向用户,使用空间滤波和波束零陷技术.(Mobile communications in the smart antenna system source code, user-oriented beam, the use of spatial filtering and beamforming technology Null.)

针对通信侦查课题，通过已知先验知识和截获信号，进行找出同步序列，匹配滤波，校正频偏和相偏，均衡，解交织，译码，恢复出原序列，最终得到的序列与原序列作对比得到误码率为0(Investigation subject for the communication, by known a priori knowledge and intercepted signal conducted to identify the synchronization sequence, the matched filter, correcting frequency offset, and phase deviations, balanced, deinterleaving, decoding, to recover the original sequence, the resulting sequence with the original sequence compared error rate is 0)

说明：  模拟调制识别各特征参数随信噪比变化曲线。信号的瞬时信息包括瞬时幅度、瞬时相位、瞬时频率及其不同角度的统计特征值，其中瞬时幅度、瞬时相位、瞬时频率是一个信号最基本的特征。（AM、DSB、SSB、VSB、FM、AM-FM）(Simulated Modulation Recognition Curve of Variation of Characteristic Parameters with Signal-to-Noise Ratio)
