Design and implementation of localization of high-speed communication system

为了提高通信系统的可靠性与传输速度,增加传输距离,降低系统的误码率并达到国产化的目的,创新性的设计的双路冗余与CRC相结合的算法并利用包括国产FPGA在内的国产器件,完成一套高可靠性高速通信系统的全国产化系统设计。经过多种复杂场景下的应用与测试,传输速度由原系统的0.4 Gbit/s提升至1.25 Gbit/s,单路传输提升为双路冗余传输提升了系统可靠性,传输距离由原系统的40 m提升至100 m,误码率降低为0。达到了复杂环境下保持高可靠性、高速、远距离、零误码率以及国产化的目的。目前已在某项目中得到应用。

In order to improve the reliability and transmission speed of the communication system,increase the transmission distance,reduce the BER of the system and achieve the purpose of localization,the innovative design of dual redundancy and CRC combined algorithm and the use of domestic devices,including domestic FPGA,to complete a set of high reliability high-speed communication system of the fully localized system design.After a variety of complex scenarios and tests,the transmission speed was increased from 0.4 Gbit/s to 1.25 Gbit/s,the single channel transmission was upgraded to dual channel redundancy transmission to improve the system reliability,the transmission distance was increased from 40 m to 100 m,and the BER was reduced to 0.The system achieves high reliability,high speed,long distance,zero BER and localization in a complex environment.The purpose is to maintain high reliability,high speed,long distance,zero BER and localization in complex environment.It has been applied in a project.
