采用广义旁瓣抵消（GSC）自适应波束形成方法实现时域和频域滤波，采用LMS自适应算法，最终实现语音增强。（文件中包含纯净语音及不同信噪比的带噪语音）-Generalized sidelobe canceller (GSC) adaptive beamforming method to achieve time-domain filtering using the LMS adaptive algorithm, and ultimately the speech enhancement

一个OFDM 基带信号，采用256点IFFT,子载波采用8PSK映射,加保护段，调制信号采用“削顶”方法降低PAPR,FIR 半带滤波，最后输出时域信号/频域响应。包含各级的视频域比较-An OFDM baseband signal, using the 256-point IFFT, the sub-carrier using 8PSK mapping, plus the protection section, the modulated signal " cut top"
