基带传输系统中AMI码性能分析与仿真

Analysis and Simulation of AMI Code Performance on Baseband Transfer Systems

以AMI码基带传输系统模型为基础,对AMI码的误码率和功率谱密度进行了求解和分析,并使用SIMULINK构建出了AMI基带传输系统仿真模型,应用该仿真模型对求解的AMI码误码率和功率谱密度进行了验证,同时讨论了AMI基带传输系统的性能与眼图的关系及码速率与带宽的关系.这将为以AMI码基带传输为通信方式的通信系统性能分析提供基本依据.

In this paper,the error rate and power spectrum density of the AMI code are computed and analyzed based on AMI transfer system model,and the simulate model of the AMI transfer system is constructed based on the SIMULINK.Using the simulate model,we test the error rate and power spectrum density of the AMI code,and discuss the relation between the property of the AMI transfer system and Eye Diagram and the relation between the symbol rate and broadband.The formulas provide theoretical evidence for the anti-noise performance analysis of the communication system.
