| Abstract: | Aiming at multipath fading effect of low -voltage power line communication channel,based on analysis the noise,fading and multipath characteristic of low-voltage power line communication channel,puts forward the solution of using diversity technology reduce the error rate of thecommunication system,and using a matrix laboratory verifies its model by simulation method. Thesimulation result shows that using diversity technology the power communication system with mini- mum shift-frequency keying modulation can resist multipath effect. |
