Interference management method based on interference regeneration in wireless communication system

Abstract

The invention belongs to the technical field of wireless communication, and discloses an interference management method based on interference regeneration in a wireless communication system. transmitters share channel state information and data information, and the transmitter corresponding to an interfered receiver builds an interference regeneration signal according to the information; the transmitter corresponding to the interfered receiver sends the interference regeneration signal, the interfered receiver performs matching and filtering on a mixed signal formed by interference and the interference regeneration signal, and expected data is regenerated from the interference. The method has the advantages that the interference is converted into the expected signal, and the spectrum efficiency of the interfered receiver is improved by using the interference energy, and can be used for solving the interference problem in wireless communication; an IRC signal used for regenerating the interference is built at a micro-micro base station PBS by using a relative expression relationship between data symbols, and the expected signal of PUE is regenerated from the interference after filtering by using the mutual effect between wireless signals.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to an interference management method based on interference regeneration in a wireless communication system. Background technique [0002] At present, the commonly used existing technologies in the industry are as follows: with the development of wireless communication technologies, wireless communication networks will include various types of communication systems and carry diversified user services. With the hierarchical and heterogeneous network structure and the introduction of various dynamic spectrum sharing technologies, wireless interference has become one of the key factors restricting network performance. Therefore, the importance of interference management techniques has become increasingly prominent. For a long time, people have used resource allocation, such as time division multiple access (TDMA), frequency division multiple access (FDMA), co...

Problems solved by technology

The above-mentioned technologies need to lose part of the power of the interfering communication pair or the interfered communication pair as a price to eliminate the impact of interference, thus resulting in a decrease in the spectral efficiency of the system, which in turn leads to a decrease in system performance

[0003] To sum up, the problems in the existing technology are: the existing interference management methods still regard interference as
