Phase reversion to reduce power spectral density of multi-band UWB signals
Ultra wide-band (UWB) radio uses pulses of very short duration, thereby spreading the energy of the radio signal very thinly over several Gigahertz bandwidth. The power spectral density (PSD) of UWB signals consists of a continuous component and a discrete component. The discrete component presents greater interference to narrow-band communication systems than the continuous component. Multi-band UWB, recently proposed to IEEE 802.15.3a, divides the working spectrum into sub-bands, in each of which one waveform is used for the impulse. In this paper, we devise an efficient mechanism to suppress the discrete PSD component of multi-band UWB.
