Time hopping-ultra wideband (TH-UWB) spectrum optimization using a novel GP-DNA algorithm

This paper focuses on the TH-UWB spectrum optimization using a novel algorithm based on genetic programming and DNA computation. The proposed algorithm is attractive due to its ability to generate time hopping codes for specific design criteria. DNA computation is used to find optimal time hopping codes and genetic programming is used to search for chaotic maps in functional domain. Simulation studies illustrate the effectiveness of the developed algorithm in spectral smoothing in TH-UWB spectrum. Furthermore, the GPDNA design methodology is not limited to sequence design but can be used to optimize various system design problems.
