A method for reducing signal receiving complexity, receiver and mobile terminal

Abstract

The invention discloses a method for reducing the signal receiving complexity, a receiver and a mobile terminal, and belongs to a technical field. The method comprises the steps: screening out a plurality of retained constellation points from a star map correlated with a processing layer; selecting one retained constellation point from the retained constellation points, calculating and obtaining a Euclidean distance corresponding the retained constellation point with reference to a reference layer and a decomposition result, which is obtained through channel response matrix decomposition and is corresponding to the processing layer; carrying out the traversal of a plurality of Euclidean distances which are respectively correlated with one of retained constellation points in the star map correlated with the processing layer, and then outputting the minimum value of the Euclidean distances correlated with the processing layer; judging whether the processing layer is a first transmission layer or not: enabling a second transmission layer to serve as the processing layer when the processing layer is the first transmission layer, enabling the first transmission layer to serve as the reference layer, and carrying out returning. The beneficial effects of the technical scheme are that the method reduces the processing complexity that the mobile terminal receives multipath MIMO signals, and reduces the receiving power consumption.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a method for reducing the complexity of signal reception, a receiver and a mobile terminal. Background technique [0002] In the prior art, a mobile terminal that adopts Multiple-Input Multiple-Output (MIMO) technology to transmit and receive transmission signals usually needs to map the transmission signal to a multi-layer transmission layer (Layers ) and perform a series of processing. Usually the above processing process is very complicated, and with the improvement of the MIMO demodulation dimension (for example, 16QAM or 64QAM), the complexity of the processing process increases exponentially, which leads to an increase in the receiving power consumption of the mobile terminal and reduces the power consumption of the mobile terminal. The efficiency with which a receiver receives and processes data. Contents of the invention [0003] According to the problems exi...
