Embodiment Construction

[0018] The present invention will be further described below in conjunction with specific embodiment:

[0019] A method for allocating frequency spectrum of a TV white spectrum communication system based on a WiFi chip, comprising the following steps:

[0020] Obtain available continuous spectrum resources in the target frequency band;

[0021] determining the carrier bandwidth in the acquired spectrum resource and the number of carriers corresponding to the carrier bandwidth;

[0022] Monitor whether the carrier bandwidth in the obtained spectrum resources changes, that is, whether it is from one location to another, and whether it is from one moment to the next moment. If the carrier bandwidth does not change, continue to monitor, and if the carrier bandwidth changes, go to Next step;

[0023] According to the changed carrier bandwidth and the number of carriers corresponding to the changed carrier bandwidth, determine the required spectrum resource and spectrum resource o...

Abstract

The present invention discloses a WiFi chip-based television white spectrum communication system spectrum allocation method. The method comprises the following steps that: available continuous spectrum resources in a target frequency band are obtained; and carrier bandwidth in the acquired spectrum resources and the number of carriers corresponding to the carrier bandwidth are obtained. According to the method, whether the carrier bandwidth in the acquired spectrum resources changes is judged through monitoring in a spectrum allocation process, and therefore, the problem of concealment exposure can be avoided, and the probability of interference on a user can be decreased, and the probability of the generation of the interference of a television white spectrum communication system can be further reduced.

Description

technical field [0001] The invention belongs to the technical field of digital television and wireless communication. In particular, it relates to a spectrum allocation method for a TV white spectrum communication system based on a WiFi chip. Background technique [0002] The problem of frequency planning is more complicated. Ideally, adjacent cells should operate at different frequencies. In the downlink, it is possible that terminals at the edge of a cell can receive transmissions from adjacent cells. to interference. In the uplink, the interference of the base station to the base station will cause the dislocation of the TDD frame, which seriously threatens the base station. This is because different base stations can select different TDD time slices in the cell according to traffic. In this way, a signal transmitted by one base station is received by another base station. Propagation tends to be better from one base station to another, since both can be at a higher l...
