认知无线电网络中衰弱信道下的频谱感知算法，基于能量检测。-In cognitive radio networks, spectrun sensing algorithms under shading channels based on energy detection

使用modulation spectrum的方法分解语音再合成，语音分解之后可以进行各种操作达到不同的音效，也可以做声源分离。(Modulation spectrum is emerging as a novel sound representation which has found applications in both ASR as well as most recently in audio coding.)
