Abstract

The embodiment of the invention discloses a data processing method which is used for solving the problem that in a multilayer system, the good throughout capacity can not be realized through a traditional minimum mean square error (MMSE) algorithm and used for improving the demodulation quality. The data processing method is applied to a multi-antenna system which comprises a data receiving architecture, wherein the data receiving architecture comprises multiple-input and multiple-output (MIMO) demodulation. The method comprises the steps that firstly, user equipment (UE) acquires a first equivalent channel matrix and first data; secondly, the UE decomposes the first equivalent channel matrix to acquire a second equivalent channel matrix; thirdly, the UE demodulates the second equivalent channel matrix through a matrix decomposition maximum likelihood QRM algorithm, and second data are acquired according to the first data; fourthly, the UE demodulates the second equivalent channel matrix through the MMSE algorithm, and third data are acquired according to the first data; fifthly, the UE acquires fourth data according to the second data and the third data.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data processing method and device. Background technique [0002] The future communication technology system requires to accommodate as many users as possible within a certain frequency band, and the data transmission rate will reach 10-100Mb / s. It is an important way for third-generation and future communication systems to achieve high data rates and improve transmission quality. It fully exploits space resources, uses multi-antenna systems to achieve multiple transmissions and multiple receptions, and doubles the capacity of communication systems without increasing bandwidth. Channel reliability is greatly enhanced. [0003] Currently, in a multi-antenna system, it is assumed that a transmitting end has T transmitting antennas, and a receiving end has R receiving antennas. System model such as figure 1 Shown: The model of the received signal is expressed by t...
