Embodiment Construction

[0046] For any kind of transmission system in communication, the signal reaches the receiving end through the propagation channel. Only by analyzing and mastering the characteristics and essence of the channel can we propose solutions to existing problems and improve the effectiveness, reliability and security of the communication system. sex. Therefore, accurate knowledge of wireless channel fading characteristics is a prerequisite for wireless communication system research. Only after fully studying and understanding the channel characteristics of the designed system can we adopt various physical layer technologies that are suitable for it.

[0047] The described storage in the computer through the PCI-E interface is stored in the solid-state hard disk, and the storage technology adopted is continuous storage.

[0048] Due to the two factors of continuous storage rate and invalid storage load in the prior art, the channel measuring instrument will not be directly used for mu...

Abstract

The invention provides a multi-antenna channel measurement data collection method based on a virtual consecutive storage mode and a multi-antenna channel measurement data collection device based on the virtual consecutive storage mode and relates to the field of wireless communication. The method comprises the following steps: setting a buffer region depth Q, collecting a group of data packets, injecting the data packets into a buffer region and storing the data packets into storage equipment; meanwhile, continuously collecting but not storing data by taking the depth Q as a unit, recording the quantity of the collected data packets, moving an antenna array, collecting a group of data packets, injecting the data packets into the buffer region and storing the data packets into the storage equipment, recording the quantity N of interval data packets between the currently-collected data packets and the front group of collected data packets, repeating collection and storage processes, recording all the collected data packets and the interval data packets and supplementing data of all the interval data packets by use of a zero filling manner. In order to solve the technical problem, the invention furthermore provides a control device based on the method. The method and the device can be used for alleviating the pressure on solid-state disks due to consecutive storage, eliminating invalid storage and improving the storage efficiency of the solid-state disks.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and device for collecting channel measurement data in a virtual storage mode. Background technique [0002] With the development of wireless communication technology, the bandwidth of the communication system has gradually evolved from the previous tens of KHz to the 3-5MHz bandwidth of 3G, and then to the 20MHz bandwidth of LTE. The transmission bandwidth of the fifth-generation mobile communication in the future may reach hundreds of MHz or even The order of magnitude of GHz. At the end of 2010, Thomas L. Marzetta, a scientist at Bell Laboratories, proposed a massive multi-antenna (Massive MIMO, Large-scale MIMO, Hyper MIMO, Full-Dimension MIMO, or ARGOS) technology (hereinafter referred to as Massive MIMO). With the development of research, large-scale multi-antenna technology has gradually become a research hotspot in the field of wireless communication in rece...
