Fast and Low-Complexity Frame-Level Synchronization for Direct-Sequence Transmitted Reference Receivers
In this paper ,we proposed and analyzed a frame-level synchronization (FLS) algorithm for the UWB direct-sequnce transmitted-reference (DS-TR) receiver. In DS-TR systems, Symbol-level synchronization is not enough for data modulation , the position of low duty cycle signal in each frame is still unknown. The algorithm which we proposed has a moderate accuracy but a very low complexity and fast synchronization speed compared with conventional approaches requiring subnanosecond-level accuracy. Detailed analysis of the algorithm is carried out based on our in-depth analysis.
