A NEW MODULATION SCHEME FOR IR-UWB COMMUNICATION SYSTEMS被引量：1
《Journal of Electronics(China)》2009年第4期497-502,共6页Wang Feng Xu Chengqi Zhang Yan 
Since the poor performance of orthogonal binary Pulse Position Modulation (PPM) compared with binary Pulse Amplitude Modulation (PAM), this paper presents a new modulation scheme named Pulse Width Modulation (PWM) for...
