Abstract

The invention discloses a simulation test system of a large-scale MIMO system. The simulation test system comprises universal software radio peripherals (USRP), a high-speed serial computer expansion bus standard PCIe case and a high-performance universal processor, wherein the PCIe case comprises a plurality of main PCIe cases and a plurality of sub PCIe cases; one main PCIe case is connected with a plurality of sub PCIe cases; one sub PCIe case is connected with a plurality of USRPs; each USRP is used for collecting antenna data and sending the collected antenna data to the sub PCIe case connected with the USRP; each sub PCIe case is used for collecting the received antenna data and sending the collected antenna data to the main PCIe case connected with the sub PCIe case; and each main PCIe case is used for collecting the received antenna data and sending the collected antenna data to the high-performance universal processor connected with the main PCIe case, so that the high-performance universal processor processes the received antenna data to obtain a processed baseband signal.

Description

technical field [0001] The present application relates to the technical field of wireless communication, in particular to a simulation test system of a massive MIMO system. Background technique [0002] At present, many studies have been devoted to building a test and evaluation platform for Multiple Input Multiple Output (MIMO) and massive MIMO systems. S. Sun et al. built a MIMO system in the millimeter wave environment, analyzed the channel characteristics of the millimeter wave environment, and made a detailed evaluation of the cell and user spectrum efficiency. Ove Edfors and others developed a massive MIMO system LuMaMi based on the hardware platform of National Instruments (NI, national instruments). Shepard C et al. developed a prototype verification system Arogs for massive MIMO beamforming. [0003] However, the above-mentioned platforms are not open at the software level for research on massive MIMO, and the hardware equipment is expensive, has a high threshold,...
