Abstract
Time Hopping Ultra Wide Band (TH-UWB) commonly encodes the data symbols by shifting the position of the transmitted pulses by a quantity that is quantized over the interpulse interval range. In this paper, we relax the hypothesis of a discrete value for the time shift introduced by the TH code, by considering the possibility of generating real-valued codes that introduce time hopping in a "fluid" way. The effect on the power spectral density of generated signals is analyzed, and potential application of fluid coding to multiple access and to network coexistence are discussed, with the awareness of the consequent increased complexity of the receiver. © 2005 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
