人工蜂群算法 matlab 实现，人工蜂群算法源代码(Artificial bee colony algorithm matlab implementation)

spectrum sensing paper energy detection very useful ...book

近场MUSIC算法，利用多重信号分类方法把位于近场的声源信号进行方位估计。(Near-field MUSIC algorithm, the use of multiple signal classification method put field is located near the sound source signal DOA estimation.)

matlab的绘图程序，希望对大家有用。(matlab drawing process, in the hope that useful to everyone.)

信号包络，提出信号包络，便于观察信号波动过程，非常有用(Signal envelope, put forward the signal envelope, easy to observe the process of signal fluctuations, very useful)
