This paper presents and studies three frequency-domain models for optimizing source pulses and detection templates in ultrawide-band (UWB) radio systems. The optimization aims mainly at maximizing the equivalent isotropically radiated power band efficiency in the free space and the output of correlation detection at a receiver. These models are based on the differential evolution, an improved version of the genetic algorithm, and carried out on a set of UWB signals with given mathematical forms. As examples, these models are used to optimize the UWB signals for both narrow-band thin-wire and wide-band planar antenna systems. In addition, the optimized results are validated by nonoptimization simulation.
