Study of Selection of Timing System External Clock Synchronization Methods Based on Matrix Switch Technology

摘要

The clock synchronization signal source of timing system is not equivalent to the receiving antenna. By using of matrix switch in the down link, and selecting the mean and variance characteristic parameters of the received signal, the performance of the work is evaluated. Using the corresponding software decision-making procedures, the optimum seeking method is automatic selected from the three signal demodulation boards. Experimental results show that the method has the merits of software automatically configuring, short switching time, overall better performance and so on.
