英文摘要：

The underpinning wireless transmissions systems of DPMR-TD and DMR-FD are analyzed,and the performance of the two systems is compared through analyzing their Bit Error Rate. The authors establish a simulation platform for point-to-point transmission links to compare the Bit Error Rate performance of the two systems.
