Analysis of PC and SGA models for an ultra wide-band ad-hoc network with multiple pulses

Abstract

The performance of six different shapes of pulses is compared for Packet Collision (PC) and Standard Gaussian Approximation (SGA) communication systems, based on the requirements of the Federal Communications Commission (FCC) emission mask. The shapes are a second derivative sinusoid Gaussian pulse, a second order Gaussian pulse and the first four orders of modified Hermite pulses. For the SGA model, the performance of time-hopping (TH) pulse position modulation (PPM) and pulse amplitude modulation (PAM) are compared, in terms of Bit Error Rate (BER). For the PC model, we investigated pulse position modulation (PPM) to analysis the performance from the energy attenuation issue. Results show that the zero order modified Hermite pulse outperforms other pulses in terms of BER in the PC model. It is also found that the performance of both the PC and SGA models will get worse as the number of users increases. The results can be applied to deal with interference issues in wireless body area networks (WBAN) in field of remote health monitoring and telemedicine systems design.
