A new design of reconfigurable sub-nanosecond pulse generator (PG) with pulse shape selection ability is presented in this paper. Step recovery diode is used as the pulse sharpening device and the pulse shaping circuit consists of a controllable RC differentiator in which a single PIN diode is embedded, which provides two different switchable pulse shaping performances. The realized PG has a compact (10 × 12 mm2) simple structure and is easy to implement while generating Gaussian and monocycle pulses with 510 and 660 ps pulse width, respectively. The proposed pulse shaping method is versatile and can be effectively modified and reconfigured to generate more complicated pulse shapes such as polycycle signals. The measured results reveal that the proposed reconfigurable PG is suitable to be used in systems with pulse shape modulation that require sub-nanosecond pulses at low pulse repetition rates.

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.
