“…The results obtained above also shows significant improvement in terms of bit error rates at the higher values of (Ex/No/ dB) and are better in comparison to the results presented in [26] and [28] for the multiple access modulated system over the multipath channel. The Also, the above results obtained for the selective Rake and Partial rake receiver configurations with two branches show that the ultra wideband system using proposed combined pulse shapes performs better than the gaussian derivative pulse shape generally used by the researchers to generate the transmission signal as in paper [15] and [23].…”

Ultra-wideband (UWB) uses very low energy levels to transfer data at very high data rate and bandwidth. An optimal and correct choice of transmission pulse shape is an important criterion in this technology. In this paper, we will present an approach for the generation of an optimal pulse shape with the optimal generation of pulse shape values that can provide effective results when transmitted using multiple access modulation technique over a multipath channel and received by a RAKE type receiver. The bit error analysis of constructed model is also given using Ideal Rake, selective RAKE, and partial RAKE receiver configurations.

“…The binary bits to be transmitted are added with a user specific pseudo code before sending them to the pulse position modulator. These pulses sequence are positioned at jTs in a specific time hopping slot according to the code (cjTc) along with the pulse shift introduced by the pulse position modulator to modulate the bits [24]. The signal at the output of the transmitter is represented as…”

Ultra-Wideband (UWB) technology uses very narrow pulses of nano-seconds duration to provide very high data rates. The pulses to be used for the UWB are very important and should meet the emission mask regulatory requirements to get good performance when transmitted over the channel. To meet these requirements, a combination of higher order derivatives of Gaussian pulses can be considered to form a combined pulse instead of transmitting them separately. The main aim of this paper is to improve the performance of Ultra Wideband (UWB) multiple access modulation system with a newly Proposed combined pulse, generated using a modified random pulse combining of the first five Gaussian derivative pulses with optimal shaping factors as basic functions. In order to meet the UWB power spectrum regulations, the power spectral utilization of the newly designed pulse is calculated and the bit error rate performance of the pulse position modulation time hopping system using the newly proposed pulse is analyzed in a multi-path channel environment using RAKE receiver. The simulation results carried out in MATLAB software shows that the new proposed combined pulse has higher pulse energy matching the spectral limits of UWB and an improved bit error rate performance as compared to the previous literature results.
