Abstract

The invention discloses a cooperative beam forming method based on integrated deep learning, and the method comprises the following steps: connecting a base station adopting beam forming to a cloud / central processing unit applying baseband processing, and simultaneously providing services for mobile users; for the system, formulating the training and design problems of the RF beam forming vectors of the central baseband and the base station, so that the effective achievable rate of the system is improved to the maximum extent; enabling the base station to learn a mapping from the omni-received uplink pilot and beam training results to predict an optimal RF beamforming vector for the base station; enabling the base station to select its beamforming vector from a predefined codebook; and enabling the central processor to design its baseband beamforming to ensure coherent combination of users. According to the method for integrating the dense neural network and the deep learning, the characteristics of different models and the strength of the model fitting degree and the prediction data effect are analyzed.

Description

technical field [0001] The invention relates to the field of beamforming, in particular to a cooperative beamforming method based on integrated deep learning in millimeter wave massive MIMO communication. Background technique [0002] mmWave and massive MIMO are key enabling technologies for current and future wireless systems due to their extremely high data rates and multiplexing gains. However, to support highly mobile users to ensure reliability and achieve low-complexity collaboration, a large number of antennas are required, which poses significant challenges for mmWave systems. One of the main reasons for these challenges is the large training, feedback and coordination overhead associated with large channel matrices. However, these channels are intuitively some function of the environment geometry, building materials, transmitter / receiver locations, etc., which can be exploited by exploiting the low-overhead nature of the environment and user settings and learning ...
