Signal simulation method and device of wireless connection physical layer convergence protocol preamble

Abstract

The invention belongs to the technical field of wireless communication testing, and provides a data signal simulation method and device of a wireless connection physical layer convergence protocol preamble. The method comprises the following steps: in a multi-user transmission scene, acquiring MAC layer data and transmitting the MAC layer data to a physical layer; generating a physical layer convergence protocol preamble in the physical layer; adding the MAC layer data to a physical layer convergence protocol preamble to form presentation layer protocol data; transmitting the presentation layer protocol data to realize wireless data signal simulation; the signal simulation process of the physical layer convergence protocol preamble comprises the following steps: configuring an SIG domain in the physical layer convergence protocol preamble, and integrating related parameter items of the SIG domain into a setting page in the configuration process; and the contents of the other domains are automatically calculated based on the MAC layer data and the configured parameters in the SIG domain.

Description

technical field [0001] The invention belongs to the technical field of wireless communication testing, and in particular relates to a signal simulation method and device for a wireless connection physical layer convergence protocol preamble. 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] In a wireless network based on the 802.11n / ac / ax protocol, the transmission of user data is transmitted layer by layer from top to bottom according to the protocol standard, and the data processing at the receiving end is carried out layer by layer from bottom to top. When the MAC layer data enters the physical layer, the physical layer will calculate and generate the physical layer convergence protocol (PLCP) preamble data based on the MAC layer data, and append the MAC layer data to the PLCP preamble to form PPDU data, and then pass the carrier Modulat...

AI Technical Summary

Problems solved by technology

[0004] The inventors found that the signal simulation efficiency of the preamble of the physical layer convergence protocol of the wireless connection is low at present, and the main reason is that in the signal simulation process of the preamble of the physical layer convergence protocol, the definition and description of the parameters based on the protocol standard are not fully considered, and the parameters of each parameter are not fully considered. Reasonable classification makes the parameter category and setting process confusing, and there are unnecessary page switching operations in the parameter setting process, which makes the process of generating PLCP leading data take more time, thereby reducing the efficiency of wireless data communication testing
