Problems solved by technology

On the one hand, the verification system can only be verified for the lognormal channel model and cannot be extended to other channel models, which limits its wide use
On the other hand, only selecting two points for statistics will bring large errors, making the verification results greatly affected by accidental elements

Abstract

In order to solve at least one of the problems in the prior art, the present disclosure provides a statistical channel model verification method and device, which can verify different types of statistical channel models. The method includes: obtaining the first channel data output by the channel emulator; obtaining the distribution to be verified; generating the cumulative distribution function and the second channel data of the distribution to be verified based on the distribution to be verified and the first channel data; sorting the first channel data Obtain the first ordered channel data; sort the second channel data to obtain the second ordered channel data; generate an arithmetic sequence; obtain the third ordered channel data based on the arithmetic sequence and cumulative distribution function; based on the first ordered channel data, the second ordered channel data, and the third ordered channel data, and determine whether the distribution to be verified is satisfied. The technical solution disclosed in the present disclosure can realize verification of different types of statistical channel models, and improve applicability and practicability.

Description

technical field [0001] The present disclosure relates to the field of wireless communication, in particular to a method and device for verifying a statistical channel model. Background technique [0002] In order to accurately reproduce the complex wireless communication environment in the real world in the laboratory, so that users can test and verify the end-to-end performance of wireless devices and network facilities at a lower cost, channel simulators are essential part. Among various kinds of channel models, the statistical channel model is the most basic model. The main idea is to model the tap gain of the channel as a certain probability model, such as the classic Rayleigh fading and Rice fading channel models. For a commercial channel simulator, the correctness of the channel model is the most important factory index that needs to be guaranteed. The channel simulators currently on the market do not have a general statistical channel model verification system. ...
