IR-UWB Pulse Position Modulation and Pulse Shape Modulation Through S-V Channel Model

Abstract

This paper proposes BER analysis of Impulse Radio Ultra Wideband (IR-UWB) pulse modulations over S-V channel model. The UWB pulse is Gaussian monocycle pulse modulated using Pulse Position Modulation (PPM) and Pulse Shape Modulation (PSM). The channel model is generated from S-V model introduced by Intel lab. Bit-error rate (BER) is measured over several of bit rates. The result shows that the modulations are appropriate for both LOS and NLOS channel, and PPM has better performance in bit rates and SNR. Moreover, as standard of speed has been given for UWB, the communication is appropriate with high bit rates in LOS channel.
