摘要: According to satisfy the Federal Communications Commission (FCC) indoor and outdoor limit spectral masks, a good understanding of power density (PSD) ultra wideband (UWB) signal how it is influenced by modulation without with time hoping (TH) necessary. In this paper, PSD UWB using pulse shape (PSM) TH analyzed. The orthogonal pair modulated Gaussian waveforms, which satisfied definition FCC are considered. analyzed shown. results discussed in conclusion. I. INTRODUCTION Almost all communication systems employ sinusoidal as transmitted waveform. Its information mapped via modulation. result that well concentrated specific frequency band. It easily suppresses noise interference bandpass filter. Unfortunately, narrowband system sensitive fading. Furthermore, spectrum divided into many narrow bands causing deficient
