Embodiment Construction

[0057] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0058] Such as figure 1 As shown, a method for recovering signals at the receiving end of a massive MIMO base station based on residual homogeneous sorting technology described in the present invention comprises the following steps:

[0059] The first step is the preprocessing of the MIMO system uplink base station: set the MIMO system uplink base station to receive user equipment signals, and construct the receiving end system model. Through the system model, you can intuitively understand the sending process of the signal at the sending end and the composition of the signal at the receiving end.

[0060] The specific steps are as follows:

[0061] (1) It is assumed that the MIMO uplink system consists of a base station equipped wi...

Abstract

The invention relates to a large-scale MIMO base station receiving end signal recovery method based on residual homogeneous sorting technology, and solves the defect that the MIMO signal recovery method is too complicated compared with the prior art. The invention comprises the following steps: preprocessing of the uplink base station of the MIMO system; receiving of the signal at the sending end; calculation and processing of the signal data; and recovery of the signal data. The invention avoids the matrix inversion process, effectively reduces the computational complexity of the signal detection process, improves the convergence rate of the signal detection, and has better bit error rate performance.

Description

technical field [0001] The invention relates to the technical field of MIMO base stations, in particular to a method for recovering signals at a receiving end of a large-scale MIMO base station based on residual homogeneous sorting technology. Background technique [0002] Massive MIMO technology has become one of the key technologies in the field of 5G wireless communication, attracting a lot of attention from academia and industry. MIMO technology can greatly increase the channel capacity of the mobile communication system without increasing the transmission power and bandwidth, thus effectively solving the contradiction between the increasing shortage of spectrum resources and the sharp increase in capacity demand. In 5G, Massive MIMO adds more antennas, which has obvious performance advantages, but as the number of antennas in the system increases, the complexity of the detection method increases. The purpose of signal detection is to restore the transmitted signal at t...
