Noise Suppression in 94 GHz Radar-Detected Speech Based on Perceptual Wavelet Packet

A millimeter wave (MMW) radar sensor is employed in our laboratory to detect human speech because it provides a new non-contact speech acquisition method that is suitable for various applications. However, the speech detected by the radar sensor is often degraded by combined noise. This paper propos...
