Abstract
In this paper, the simple waveforms for ultra wideband (UWB) communications are presented to satisfy the Ministry of Internal Affairs and Communications (MIC) spectral mask. The rectangular passband, modulated rectangular and modulated Gaussian waveforms are considered. They are optimized to maximized bandwidth, amplitude and average power in the MIC spectral mask bandwidth ranging from 3.4 to 4.8 GHz for low passband and 7.25 to 10.25 GHz for high passband. The maximum average power spectral density (PSD) limit of MIC spectral mask is considered. The binary pulse amplitude modulation (PAM) with balance binary data independent identically distributed (i.i.d.) random sequence is considered to easily derive the PSD of the waveforms. The PSD and parameters of each optimized waveforms are shown. The optimized results are discussed in the conclusion
