Problems solved by technology

[0004] However, when analyzing 5G NR signals, the interface of the current 5G NR demodulation analysis software requires users to manually configure a large number of parameters, and the parameters that can be automatically demodulated also need to select the automatic mode, and the demodulation speed in the automatic mode will slow down, resulting in The adjustment efficiency is low; if the configuration of one of the parameters is inconsistent with the parameters set on the 5GNR signal interface, it will cause incorrect demodulation results such as high EVM value and constellation diagram divergence; when analyzing the cause of the wrong result, it is impossible to quickly locate the configuration wrong parameters

Embodiment 1

[0033] This embodiment provides a 5G NR signal demodulation method that automatically configures public parameters, such as figure 1 shown, including the following steps:

[0034] Step 1. Obtain the 5G NR signal generated by the signal source and the encoding of the common parameters.

[0035] The signal source that generates the 5G NR signal and the signal analyzer with the 5G NR signal demodulation function are connected through a cable. After the signal source generates the signal, the common parameter items are encoded at the signal source and transmitted to the signal analyzer. In order to maintain the generality of the fast configuration method, the encoding method adopts the Polar encoding process in Section 5.3.2 of 38.212 of 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project). By counting the common parameter items of the signal source and the analyzer, the encoding process specified by the 3GPP protocol is multiplexed, so that any analyzer ...

Abstract

The invention provides a 5G NR signal demodulation method and system capable of automatically configuring a common parameter. The method comprises the following steps: receiving a 5G NR signal sent by a signal source and a code of the common parameter; after the codes of the common parameters are decoded, the common parameters are obtained and displayed; obtaining a non-public parameter configured by a user, and splicing the public parameter and the non-public parameter to obtain a parameter required by demodulation; and demodulating the 5G NR signal by adopting a demodulation algorithm on the basis of the parameters required for demodulation. The problem that in the 5G NR signal demodulation process, the configuration process of inputting a large number of parameters on an instrument interface is complex and tedious is solved.

Description

technical field [0001] The invention belongs to the technical field of 5G NR signal analysis, and in particular relates to a 5G NR signal demodulation method and system for automatically configuring public parameters. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The three major application scenarios of the fifth-generation mobile communication new air interface (5G NR) signal are enhanced mobile broadband (eMBB), ultra-reliable and low-latency communication (uRLLC) and massive machine type communication (mMTC). Compared with the fourth-generation mobile communication (4GLTE / LTE-A), these three application scenarios put forward higher requirements for key performance indicators such as peak rate, spectral efficiency, user experience rate, delay, and power consumption. Therefore, the 5GNR test puts forward higher requirements for the 5GN...
