AbstractThis paper presents an overview of a digital PCM adaptive bit synchronizer capable of bit synchronization down to an Eb/No of -20 dB where Eb/No is the energy contrast ratio. The topics addressed include: 1. Functional block diagrams. 2. Loop bandwidth as a function of synchronization threshold. 3. Accuracy, resolution and stability requirements of the Numerically Controlled Oscillator (NCO) and Loop Filter (LF). 4. Performance data. The purpose of this paper is to highlight the major components of a unit capable of performing this task based on an actual development program.
