A Novel pulse shaping for UWB impulse radio IEEE 802.15.4a communications systems

This paper presents a novel pulse shape which we call modified triangular pulse (MTri) for Impulse Radio-Ultra Wide Band (IR-UWB) IEEE 802.15.4a systems. The MTri pulse and UWB shapes previously proposed for low power IR-UWB transceivers topologies are studied and compared. The performance measures considered are compliance with required spectral emission constrains, Mask Loss (ML) power and pulse energy. Our theoretical and simulations results show the advantages of the MTri pulse over studies UWB pulses. It presents the lower ML power about 0.45dB and the higher pulse energy of 0.45nJ/p.
