Abstract :
We derive the power spectral density of time-hopping (TH) spread-spectrum signals in the presence of random timing jitter. Detailed descriptions of different TH schemes, employing a random TH sequence, are given and spectral analysis of such TH signals in the presence of uniform timing jitter is carried out using a systematic and tractable technique.
