Research on Middle Voltage Power Line MIMO-OFDM Low Complexity Communication Strategy Based on Group Division

摘要

In order to improve the transmission efficiency of the middle voltage power line MIMO-OFDM communication system, a low complexity communication strategy based on group division is proposed. Firstly, this paper introduces the MIMO-OFDM transmission strategy based on SVD. Then, the basic idea of bits and energy allocation based on group division and its implementation are described. Finally, the simulation is carried out comparing with the method without group division strategy. Simulation results show that the proposed strategy can reduce the complexity of bits and energy allocation and improve the transmission efficiency of MIMO-OFDM system under the condition of low bit error rate in middle voltage power line communication system.
