| Abstract: | 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. |
| Keywords: | baseband transfer system AMI code error rate power spectrum density SIMULINK |
