Abstract

The invention relates to a method and system for predicting spectrum noise of a power wireless private network. The method includes obtaining frequency spectrum noise power of a set frequency in a settime period; determining a Markov chain model of frequency spectrum noise prediction of the power wireless private network according to the frequency spectrum noise power; and utilizing the Markov chain model of frequency spectrum noise prediction of the power wireless private network to predict the occurrence probability of frequency spectrum noise at a next moment in the future. The method forpredicting spectrum noise of the power wireless private network utilizes a frequency spectrum noise power value set of a certain frequency detected in a known period of time at fixed time intervals, and adopts the Markov chain model to predict the frequency spectrum noise of the certain frequency at the next moment.

Description

technical field [0001] The invention relates to a spectrum noise prediction technology of a power wireless private network, in particular to a spectrum noise prediction method and system of a power wireless private network. Background technique [0002] The 1.8GHz frequency band is one of the spectrum resources used in the construction of electric power wireless private networks. This frequency band is shared by industries such as energy, rail transit, and aviation. Moreover, the deployment environment of power terminals is complex, and there are various sudden interferences in spectrum resources. This sudden interference often has a certain regularity. For example, the communication of wireless equipment in other industries and the communication of wireless equipment in neighboring areas will cause sudden interference, but it has a strong regularity. For example, the traffic flow near the expressway, the traffic flow of the high-speed rail, and other nearby production and l...
