The rapid development of smart distribution has brought great challenges for power line carrier technology,while the traditional protocol standards can not meet the requirement of distribution network,such as G3-PLC,PRIME,HomePlug,G.9960,IEEE P1901and so on.A new generation device of power line carrier communication is designed independently with OPDM technology.The bandwidth of the device can be flexibly adjusted between7.8kHz to10MHz,and the processing units of physical and front-end are implemented in FPGA chip and MAC/convergence processing units work in ARM chip.Both attenuation of signals power and signal distortion rate accord with the requirement of the relevant standards,and test results verify that the research and developed device has a good stability and accuracy when it works.
