Research of waveform design based on UWB pulse signal

The optimization design of UWB wireless communication waveform pulse not only be able to improve the bit error rate （BER） performance, but also can optimize the design of UWB wireless system,improve power efficiency and reduce interference , which make UWB wireless communication system and other traditional communication systems coexistence. Pulse waveform in UWB system plays an important role and has a great significance. The paper, in accordance with the characteristics and demands of uhra-wideband system, advanced specific requirements and related evaluation of forming pulse design and introduced some typical UWB pulse shapes, including the principles and characteristics of Gaussian pulse and its derivative pulse, Hermite orthogonal pulse and Prolate spheroidal wave function orthogonal pulse. It finally introduced some attention matters in the process of pulse sbape design.
