Multichannel Transmission Technique for Power Frequency Communication of Distribution Network
摘要
Abstract
Power frequency communication is a special communication technology based on distribution network,however there is the defect of low data rate. For this reason,according the fact that the phase angle difference between voltages of arbitrary two-phases is 120°, an idea of three-phase cyclic modulation and receiving is proposed. In sinle-phase multichannel transmission, an orhocode block method for uplink signal of power frequency communication is given, namely by means of Hadamard matrix the orthogonal detection vector suitable to power frequency communication is extracted and from the orthogonal detection vector the modulation and encoding mode of signal is attained Finally, the structure of a multichannel transmission system for power frequency communication is proposed and the feasibility and effectiveness of the proposed system are verified by on-site testing.关键词
