Synchronization scheme in non-coherent demodulator for TDMA digital mobile radio system

Abstract

Symbol timing recovery, frame synchronization and frequency offset compensation are essential synchronization circuits in noncoherent demodulator for TDMA digital mobile radio system. In this paper, we present a synchronization scheme, combined with a nonlinear symbol timing recovery using Gardner's timing error detector, a baseband feedback frequency offset compensation, and a simple frame synchronization using a code-matched correlator and a peak detector with a suitable threshold.
