Suitability of FH codes as TH codes for multiuser UWB Systems

Abstract

In this paper performance of four frequency hopping (FH) code sequences has been studied from the point of view of evaluating their suitability for time hopping (TH) UWB systems. Multiuser interference analysis and correlation properties of the code sequences have been considered as the tools to derive the final conclusions. The paper also provides the lower bound on the correlation measure of TH codes.
