Abstract

In order to solve the problem about the clock synchronization and high precision in the TDOA location system, a clock synchronization scheme was designed. In the article, the GPS+TCXO clock module was used as the front end of the reference clock source, and the PLL + clock buffer solution was used in the back end. The effect of the clock and ADC was analyzed on the TDOA location system; the system hardware designs were analyzed, such as the selection principle of the reference clock source and the PLL clock hardware circuit design and the parameter selection basis; the synchronous sampling method of the system clock and the register allocation process through the FPGA logic were introduced. The experimental result showed that the proposed scheme can reduce the clock jitter and improve the accuracy and stability of the input clock.
