Problems solved by technology

The optimal detection algorithm has the best performance, but the complexity of the algorithm is too high, and it is not suitable for the actual communication system
The suboptimal detection algorithm reduces the complexity of the optimal detection algorithm, but its performance is also lower than the optimal detection algorithm, and it is still not suitable for scenarios that require high system speed
The linear detection algorithm is less complex, but has the worst performance

Embodiment Construction

[0041] A kind of detection method based on IEEE 80211ac radio frequency test system receiver provided by the present invention comprises the following steps:

[0042] 1) For the received signal at the receiver, after steps such as synchronization, frequency offset estimation and compensation, and SIG field analysis, use the VHT LTF field to perform least squares channel estimation to obtain the channel matrix;

[0043] 2) Carry out the Gram Schmidt orthogonalization process of correcting the channel matrix obtained in step 1), obtain the result of QR decomposition, and use the traditional layer-by-layer interference elimination algorithm to complete the detection, and obtain the initial detection result. The specific steps are:

[0044] 2.1) The Gram Schmidt orthogonalization of the channel matrix is ​​modified. Different from the traditional QR decomposition process, in the process of orthogonalization, it is necessary to make the diagonal elements of the R matrix from small t...

Abstract

The invention provides a receiver detection method based on a 80211ac RF consistency testing system. The method comprises the steps of supposing a fact that a channel matrix is known, performing QR decomposition detection based on corrected Gram Schmidt orthogonalization on the channel matrix H, and obtaining a decomposed matrix Q, a decomposed matrix R and an initial detected value matrix; afterwards, determining whether the matrix R are ideal matrixes, and if not, eliminating interferences of partial signals from the system, utilizing a zero forcing detection algorithm on the new system, and updating and rearranging an existing detection result. On condition that an ideal solution is not obtained by means of traditional SQRD detection, the receiver detection method performs functions of updating detected data by means of the zero forcing detection algorithm after system reconstruction, improving performance of the traditional SQRD detection algorithm, and improving EVM index of an RF testing system.

Description

technical field [0001] The invention relates to an 80211ac radio frequency test system, in particular to a detection method based on a receiver of the 80211ac radio frequency consistency test system. Background technique [0002] Wireless local area network technology has developed rapidly in recent years. It uses radio frequency technology to realize convenient transmission of information. Compared with wired networks that require wiring, wireless LAN technology has the advantages of convenient installation, easy network planning and adjustment, and easy expansion, and can be well integrated with Internet services to provide users with convenient high-speed Internet services. Because of this, wireless LAN technology has experienced several generations of development such as 802.11a, 802.11b, 802.11g, and 802.11n. Now, the fifth-generation wireless LAN standard IEEE 802.11ac proposal has been proposed. 802.11ac is called "Very High Throughput (Very High Throughput)", and i...
