Soft noise filtering and received signal balance methods in high-load environments of fifth-generation radio base station equipment systems

Abstract

This invention relates to a method for soft noise filtering and signal balancing in high-load environments of a fifth-generation radio base station system, including: calculating and selecting diversity reception direction and phase-coherent weighting values ​​for the reception direction of 32 antenna array data paths to receive eight data streams according to load density distribution; The data balancing is performed after synthesizing the frequency domain and multiplying the input data with a signal filtering coefficient distributed according to the ratio Ue in the serving cell at 5%, 50%, and 95%; and the signal detection portion is removed after noise filtering and signal balancing is recreated using an adaptive compensation mechanism. The balanced gain is calculated based on the noise-removed data after filtering and the combined antenna weight. This gain will be maintained adaptively under loading conditions in living cells at levels of 5%, 50%, and 95%.
