Abstract

The invention discloses a data diversity combining method and device, communication equipment and a storage medium, and the method comprises the steps: selecting and reserving data for diversity combining according to the subcarrier position information of narrow-band noise and a preset selection strategy; generating a diversity combining coefficient according to the reserved data; and according to the diversity combining coefficient, carrying out diversity combining on each path of data. According to the embodiment of the invention, the data diversity combining method and device, the communication equipment and the storage medium are applied to a power line communication system, can adapt to a power line communication environment, and select and reserve data with less narrow-band noise pollution for adaptive diversity by utilizing the position relationship between the data and the narrow-band noise, thereby reducing the influence of the narrow-band noise on signals, obtaining better diversity gain, and improving the reliability of data transmission.

Description

technical field [0001] The present invention relates to the technical field of power line communication, in particular to a data diversity combining method and device, communication equipment and a storage medium. Background technique [0002] Power line communication is a communication method that utilizes currently existing wires for information transmission. Due to the advantages of low cost and low power consumption, power line communication has received great attention at present. In the power line communication system, the narrowband noise is one of the important factors restricting the communication reliability. Usually, the narrowband noise in the power line channel is a sudden high-power noise, which has a wide range of sources, including various switches, etc., and is difficult to predict and filter out. Therefore, how to reduce and eliminate the influence of narrowband noise interference on power line communication has become an important technology in the field...
