基带信号周期采样的分析与仿真设计低通信号，对该信号进行周期采样，最后从采样数据中恢复原始信号；改变采样频率，给出相应的仿真结果；考察前端抗混叠滤波器的作用和必要性；分析后端理想恢复滤波器是否唯一。( Periodic sampling of the baseband signal analysis and simulation to design low pass signal, the signal is periodic sampling, finally recover the original signal from the sampled data changing the sampling frequency, gives the corresponding simulation results examine the front of the role of anti-aliasing filter and necessity analysis backend ideal restoration filter is unique.)

针对MUSIC算法在进行信号波达方向(DOA)估计时谱峰搜索运算量大的问题,提出了一种基于FFT多波束算法与MUSIC算法的联合DOA估计方法。该方法采用FFT多波束算法形成多个波束,近似估计信号DOA,获得对应波束指向,再利用MUSIC算法实现对信号DOA的精确估计。这样就只需在该波束指向对应的空域范围内搜索,减小了DOA估计的运算量。(MUSIC algorithm for performing signal DOA (DOA) estimates peak search operation when big problem, a joint DOA estimation method based on FFT algorithm and multi-beam MUSIC algorithm. The method uses FFT algorithm for multi-beam forming multiple beams, approximate estimate signal DOA, obtain the corresponding beam pointing, reuse MUSIC algorithm for accurate estimation of the signal DOA. This will only search within the beam direction corresponding airspace, reducing the amount of computation DOA estimates.)
