摘要:

针对高速数传技术的快速发展和广泛应用，提出了一种DSP实现CPCI总线的高速数传通用接收机实现方案。该设计兼容模数混合和全数字硬件输入接口，采用ADC采样率在线设置和程序动态加载技术，可实时完成对不同码速率和不同调制编码方式数据源的解调译码。对450 Mbit/s和600 Mbit/s两种高速数传性能进行了测试，结果表明其接收机解调损失分别小于1 dB和1.5 dB，满足工程应用需求。

Abstract:

With the rapid development and wide applications of highrate data transmission technology,a CPCI bus implementation method of the general highrate data tran smission receiver is proposed by utilizing the DSP. This method is designed with hybrid analogdigital and alldigital input interfaces, and the sampling rate of ADC is set online and dynamic loading technology is adopted, which can demodulate and decode the signal source with different code rates,modulation and code schemes in real time. The 450 Mbit/s and 600 Mbi t/s receivers are measured to evaluate the proposed implementation scheme. The results show that the signa ltonoise ratio (SNR) losses of two receivers are less than 1 dB and 1.5 dB respectively, which are suitable for the practical engineering application.
