Problems solved by technology

[0004] One of the criteria for pairing multiple users is to pair based on the SINR of the paired users. However, as the number of paired users increases, the matrix inversion when solving the SINR of the paired users will become very complicated. As a result, the time consumption of solving the signal-to-interference-noise ratio of paired users will increase

Abstract

The application discloses a virtual MIMO user pairing method, system and base station. The method includes: obtaining the channel matrix, noise power and the received signal-to-noise ratio under the single-input multiple-output condition before the user pairing; according to the channel matrix, the noise power and the received signal-to-noise ratio under the single-input multiple output condition before the user pairing, and The signal-to-interference and noise ratio of each paired user is calculated by the block inversion method of the Hermitian matrix; the wireless resource allocation and the transmission modulation and coding method of each paired user are determined according to the signal-to-interference and noise ratio of each paired user. The SINR of each paired user is calculated by adopting the block inversion method of the Hermitian matrix, which can greatly improve the speed of virtual MIMO user pairing.

Description

technical field [0001] The present application relates to the communication field, in particular to a virtual MIMO user pairing method, system and base station. Background technique [0002] As we all know, multiple input multiple output (MIMO, Multiple Input Multiple Output) technology allows multiple antennas to simultaneously transmit and receive multiple spatial streams, and can distinguish signals sent to or from different spatial orientations. MIMO technology enables multiple parallel data streams to be transmitted at the same time. At the same time, using MIMO technology can significantly overcome channel fading and reduce the bit error rate. [0003] However, in some cases, the device is limited by size or hardware complexity, and often only has a single antenna, so it cannot implement MIMO technology and enjoy the benefits brought by MIMO technology. To this end, the prior art proposes a Virtual Multiple Input Multiple Output (VMIMO, Virtual Multiple Input Multiple...
