Abstract

The invention provides a pre-coding processing method, a pre-coding processing device and a base station. The pre-coding processing method comprises the following steps of: acquiring spatial channel relevance parameters of a communication system of the base station, and acquiring interference avoiding parameters according to the spatial channel relevance parameters; according to the interference avoiding parameters, acquiring an element value of a fixed element of a pre-coding matrix to be constructed; according to an interference alignment algorithm, acquiring element values of the elements in the pre-coding matrix to be constructed besides the fixed element; according to the element value of the fixed element of the pre-coding matrix to be constructed and the element values of the elements in the pre-coding matrix to be constructed besides the fixed element, constructing a pre-coding matrix; and according to the pre-coding matrix, carrying out pre-coding processing to data streams. The pre-coding processing method, the pre-coding processing device and the base station, provided by the invention, have an effective inhibition function to interference.

Description

technical field [0001] Embodiments of the present invention relate to multiple-input multiple-output technologies, in particular to a precoding processing method, a precoding processing device, and a base station, and belong to the field of communication technologies. Background technique [0002] In the field of wireless communication technology, the interference between signals is a key bottleneck affecting its development. At present, the interference between signals cannot be completely solved through technical means, such as the capacity of two-user Gaussian interference signals, etc., have not been resolved. [0003] At present, a way to solve the interference problem is to share their own channel information among the signal transmitters instead of sharing the data to be transmitted, and then use the method of interference alignment (Interference Alignment, referred to as: IA) to automatically The interference of the machine is gathered to the signal space that the co...
