Abstract:

A feedback algorithm based on digital correlation method is investigated, and it works at relatively low sampling frequency to solve multi-channel MUXDAC synchronizing problem. The principle and implementation method of the algorithm are analyzed. The influences of the parameters on accuracy are also analyzed. The algorithm has been used in a multi-channel radar AWG system, and it has been vesified that the algorithm can be implemented easily and improves the reliability of the whole system.

Key words: multi-channel DAC synchronization, digital correlation method, software radio
