Bit error rate analysis and simulation of IOT cooperative communication technology
摘要
Abstract
In order to improve the reliable transmission of internet of things communication technology,a method of relay coopera-tion is studied.A two-hop and-relay communication model is established according to the characteristics of wireless sensor network nodes in the substation operation status monitoring system.The performance of two relay forwarding protocols,and Forward(DAF)and Amplify and Forward(AAF),is analyzed,and the process of calculating the bit error rate from the source node to the node is derived.In order to further verify the impact of relay protocols and modulation methods on the transmission performance of communication systems,theoretical analysis is simulated through MATLAB programming.The simulation results show that the introduction of relay technology in the communication of substation sensor nodes can effectively improve the reliability of the monitoring system.In the two multi-branch re-lay system,the bit error rate of AAF is lower than that of DAF when multiple branches forward simultaneously.From the perspective of modulation technology Binary Phase Shift Keying(BPSK)has better noise resistance.Using AAF relay forwarding protocol and selecting BPSK as the modulation method in wireless network of the internet of things can achieve lower bit error rate.关键词
