数字移动无线电无线传输技术分析

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.%针对DMR-TD和DPMR-FD的底层无线传输系统体制进行详细介绍和对比;通过误比特率分析了2种制式无线传输系统的性能;最后建立点对点传输链路仿真平台,分析和比较了2种制式无线传输的误比特率性能。
