quick-acquisitionmethod-of-signals
主要研究了两种高动态扩频信号快速捕获的方法,即基于FFT 的频域(载波) 并行捕获法和基于FFT 的时域(伪码)
并行捕获法,并使用MATLAB 进行了仿真和比较。仿真结果表明:基于FFT 的频域并行捕获可捕获较大的频偏并跟踪一定
的频率变化率,可用于卫星变轨等高动态、高加速度等飞行过程。而基于FFT 的时域并行捕获可快速捕获码相位,用于在轨飞行的飞行器,可根据轨道参数提前预报其多普勒频偏,但同时需要精密测距的飞行过程。(Research on the quick acquisition method of the high dynamic spread spectrum signals)

Channelization_multi_phase_filter_structure
该程序是软件无线电中信道化技术的仿真历程,使用了“多相滤波结构”,将32个频率分量进行调制,平均调制在频谱之中,提升了发射信号的频谱利用率。该程序有利于对信道化与多相滤波的理解。(This program is the simulation process of channelization technology in software radio. It uses a "polyphase filter structure" to modulate 32 frequency components. The average modulation is in the spectrum, which improves the spectrum utilization of the transmitted signal. The program is helpful for understanding channelization and polyphase filtering.)
