一篇非常经典的LEACH协议改进文献，值得大家学习，在此与大家共享。(It is a very useful book that about LEACH protocol! You can study it and get you want.thank you!)

DOA估计的又一经典算法，和MUSIC相比，不需要谱峰搜索，相对更快捷！是利用空间旋转不变性求得波大方向。(DOA estimation is a classical algorithm, and compared to MUSIC, without spectral peak searching, relatively more efficient! Is the use of space rotation invariance to obtain the wave direction.)
