摘　　要：在综合无线电平台中,根据硬件平台通用化要求,需要选择一种总线同时满足CNI不同波形的中频数据传输对延时、带宽和误码率的要求。本文针对不加协议的GTX和加上高速串行通信协议的Aurora、SRIO进行测试,得到这三种高速串行总线在延时、带宽和误码率的对比分析,从而选择一种总线作为多波形综合的中频数据传输总线。In the integrated radio platform,we are supposed to meet the requirements of hardware platform generalization.Then a bus is needed to meet requirements of delay,bandwidth and error rate of all kinds of CNI waveforms.Tests have been carried out in various protocols of high speed serial bus,including Aurora,SRIO and GTX without protocol.Comparative analysis of delay,bandwidth and error rate is obtained,and a proper high speed serial bus is chosen according to the requirements of the intermediate frequency data transmission in the Integrated Radio Platform.
