Base station and signal processing method thereof

Abstract

The invention discloses a base station and a signal processing method thereof. The method which comprises the following steps: measuring an atmospheric duct detection parameter and a physical layer conventional parameter; processing the obtained atmospheric duct detection parameter and determining whether atmospheric duct interference exists in combination with the preset parameter threshold of an atmospheric duct interference detection model; determining a corresponding demodulation strategy to demodulate a uplink transmission signal according to an obtained result indicating whether the atmospheric duct interference exists; according to the obtained result indicating whether the atmospheric duct interference exists, determining a corresponding scheduling strategy and performing scheduling based on a demodulation result and a measurement result of the physical layer conventional parameter. The method deals with the influence of the atmospheric duct on the interfered base station, and well solves problems of uplink system performance reduction, seriously deteriorated wireless call completing rate, call drop rate, and handover success rate, and poor user experience of the base station, especially a TDD-LTE base station under strong interference such as the atmospheric duct in the prior art.

Description

technical field [0001] The invention relates to an interference processing technology, in particular to a base station and a method for realizing signal processing thereof. Background technique [0002] Atmospheric waveguide refers to the atmospheric space that can make electromagnetic waves return and propagate in a zigzag manner. The atmospheric space can be close to the ground, the upper wall is the stratification of the atmosphere, and the lower wall is the earth's surface; it can also be suspended, and the upper and lower walls are the stratification of the atmosphere. The appearance of atmospheric ducts is determined by meteorological conditions. Generally, it is easy to form atmospheric ducts in the atmosphere when the weather is stable and clear after rain in summer. In coastal areas, when the dry hot air mass on the land moves to the sea, it is also easy to generate atmospheric guided waves. Atmospheric ducts generally occur more in low and middle latitudes, espec...

Problems solved by technology

However, this solution has the following problems: the detection method is inaccurate, and the interference, especially atmospheric interference, cannot be effectively identified; the source base station cannot be effectively found; the source base station is found, but interference intervention cannot be effectively performed, for example, the source base station may be damaged after interference Even if the source base station is found, if the source base station is not the base station in charge of the operator, interference avoidance cannot be performed

Therefore, in many scenarios, the current scheme of finding the source base station and restricting the interference of the source base station is basically an evasion method, and cannot effectively deal with the impact of atmospheric waveguide interference on the disturbed base station
