TETRA无线收发系统的性能仿真与研究

Performance Simulation and Study of TETRA Radio System

TETRA(Trans-EuropeanTrunkedRadio)是由ETSI(EuropeanTelecommunicationStandardsInstitute)制定的一套数字集群移动通信标准。与传统的模拟集群移动通信系统相比,TETRA具有更高的频谱利用率,提供更广泛的业务服务。针对TETRA提出的无线收发系统技术指标,利用通信系统仿真软件SPW(SignalProcessingWorksystem)对TETRA的无线收发系统在几种典型的传播环境下的误比特性能进行了仿真和分析。

TETRA(Trans -European Trunked Radio)is a digital trunked radio standard b eing defined by ETSI (European Telecommunication Standards Institute).Compared with the traditional analog trunked ra-dio,TETRA is more spectrum efficien t and can provide extensive services.In this paper,the BER(Bit Error Rate)performance of TETRAin some typical propagation environments is obtain ed through computer simula-tion with SPW(Signal Processing Worksystem,a sim ulation package for communication s ystem).The simula-tion chain is set up according to the r adio specification of TETRA.
