A modified time-shared code tracking loop for frequency hopping systems

Abstract

A modified time-shared code tracking loop (MTSL) for frequency-hopped signals is presented. The tracking performance of the MTSL in the presence of white Gaussian noise is analyzed. An analytical expression for the code tracking jitter performance is derived and plotted, and the results compared to those obtained for the traditional time-shared loop (TTSL) and the traditional full-time loop (TFTL). Results show that the MTSL obtains a code tracking jitter less than those of the TTSL and the TPTL for given S/N.
