Abstract

The invention discloses a broadband power line communication subcarrier distribution method based on a quantum algorithm. The method comprises the following steps: 1, establishing a multi-node power line network topology model; 2, initializingthe coding of the quantum state; 3, forming a population; 4, measuring the quantum state; 5, evaluating target; 6, judging whether the genetic termination condition is reach; If yes, ending the method; If not, evolving by a rotation operator and returning to step 4. The invention combines the quantum genetic algorithm and adopts the dynamic resource allocation mode to optimize the distribution of the broadband PLC subcarriers, so as to improve the transmission efficiency of the OFDM system and realize the improvement of the power line communication performance.

Description

technical field [0001] The present invention relates to the field of power communication, in particular to a quantum algorithm-based subcarrier allocation method for broadband power line communication. Background technique [0002] The signal attenuation of the power line carrier signal, carrier interference and noise on the power line exist in large quantities, which makes the power carrier communication insufficient in communication distance and communication reliability, so it is impossible to effectively predict the quality of carrier communication for a long time. Since the carrier signal attenuates seriously with distance, it is necessary to rely on relay relay to achieve long-distance transmission. In order to complete the adaptive adjustment of relay nodes and relay paths, an adaptive control networking technology has emerged in recent years, that is, using dynamic routing to adapt to a dynamic PLC (Power Line Communication (PLC)) network. The proposal of this algor...
