扩频通信，从电磁波利用来看，与一般现有的常规通信方式完全不同。扩频通信利用伪随机编码把信息数据（窄带信号）的频谱进行扩展，形成宽带的低功率谱密度信号发射，使用不同的伪随机序列编码，不同通信用户可在同一频段、同一时间工作，互不影响或干扰极小地进行通信。-Spectrum, from the electromagnetic waves used term, and the general existing conventional means of communication is entirel

室内定位系统, 利用窄带高频方波信号进行室内高精度定位 -indoor localization and positioning, using high frequency squarewave to get high accuracy position on indoor environment.

基于稀疏贝叶斯学习的窄带信号波达方向估计，实测有用，亲测有效！(Based on the sparse Bayesian learning, the narrow-band signal direction estimation is useful, and the pro-test is effective!)
