channel error rate meaning in Chinese

信道差错率

In this paper , we create the network , node and process model using opnet software to simulate throughput performance of aos packet service , and choose various combinations of source packet length , transfer frame length and channel error rate to form different simulation scenarios . by analyzing the throughput - packet length , throughput - frame length simulation curves at different channel ber we get the optimal packet length and frame length configurations , and give some advice for the optimization of protocol configuration parameters according to throughput performance metric ; the complete node and process model of aos protocol have been built by opnet software , and a simple network scenario has been built to simulate and verify the validation of the protocol model
