A new resource allocation algorithm in single-user power line communication system

With the rapid distribution of smart grids in China, the power line communications (PLC) have been becoming a potential scheme to transmit data. For any kind of communications system that will be used in a large range, resource allocation is a very important aspect. This paper has analyzed the single-user bit and power allocation model with power self adaptation and speed rate self adaptation based on the constraints of self adaptive OFDM system in the single-phase power line communication, then it has proposed a kind of by bit loading algorithm and carried out simulation analysis under the typical single-user power line channel environment.
