Application of Optimal Pulse Design in Non-ideal Ultra-wideband Transmission

Abstract:
The performance of an impulse radio system depends on the pulse shape, modulation, coding, the frontend components, the channel and the receiver structure. In this contribution, a Time Hopping Pulse Position Modulation (TH-PPM) system is investigated that operates in an indoor scenario and consists of non-ideal frontend components and a correlation receiver. The question arises how the pulse shape influences the system performance, namely the bit error rate. Classical pulse shapes do not fully exploit the power spectral density regulation and lead to reduced transmit power and performance. Therefore, optimal pulse shapes are of great interest. This contribution first summarizes how optimal pulse shapes can be obtained and demonstrates in a second step how they improve the system performance if the system is assumed to be non-ideal which is neglected in most contributions.
