Analytical study on bit-synchronization problems in a coded communication system
Abstract
Many bit-synchronization techniques in digital communications depend on bit transitions for successful operation. In this paper, the four main sources of generating transitionless signals are categorized. Then the general properties of channel coding are described and it is explained that, by injecting a well-selected detectable error pattern into the transmitted and coded signal, this bit transitionless problem can be eliminated without any additional bandwidth penalty. Finally, examples in both block code and convolutional code are selected for illustrating this simple but useful application.
