Problems solved by technology

[0006] To sum up, the current two mainstream PPDU generating devices have the following deficiencies: the data processing flow described by the protocol is not fully considered, and many parameter setting items of the physical layer and MAC layer without greater logic are piled up on the setting interface, and the setting function Not intuitive enough; the logical correlation between parameter setting items is not fully utilized, the distribution of parameter items is scattered, and the complete PPDU generation process setting needs to switch back and forth between multiple setting interfaces, which affects the convenience of operation

Embodiment 1

[0037] The present invention divides the parameters generated by PPDU into two categories, that is, general parameters and physical frames. Such as Figure 4 A device for generating a physical layer protocol data unit (PPDU) based on IEEE 802.11a / b / g specifications includes a general configuration module, a physical frame block configuration module, and a tag configuration module.

[0038] Among them, the general configuration module includes basic function settings and protocol general parameter settings. Basic function settings include status switch, restore default, call files, save settings, generate wave files, etc. Protocol general parameter settings include bandwidth, sampling rate, number of antennas, etc. etc., the specific page layout design such as Figure 5 .

[0039]Wherein, the physical frame block configuration module includes a physical frame block diagram and a physical frame configuration table. The physical frame configuration table contains multiple rows...

Embodiment 2

[0045] A PPDU generation method based on a wireless connection is combined with the PPDU generation process to comprehensively sort out the protocol parameters and function parameters that affect the PPDU generation process. When designing the above-mentioned PPDU generation device, the software functions are reasonably arranged, and the configuration functions are reasonably classified to provide flexible And a comprehensive protocol parameter and software function parameter setting scheme. The method can generate PPDU data according to different signal generation modes, and display the PPDU format and the data composition of each part in a graphical manner. This method reasonably designs the parameter setting logic, so that the parameters of the setting interface are more in line with the data processing process, and at the same time, the distribution of parameter items is more compact, such as integrating the MAC header setting parameters with the PPDU data setting parameter...

Abstract

The invention discloses a wireless connection physical layer protocol data unit generation device and method, and belongs to the technical field of network protocols, the generation device comprises a general configuration module, a physical frame block configuration module and a mark configuration module; the general configuration module is divided into a basic function setting part and a protocol general parameter setting part; the physical frame block configuration module is divided into a physical frame block schematic diagram part and a physical frame configuration table part. According to the method, the PPDU data is generated by adopting the generation device, and the PPDU format and each part of data composition are displayed in a graphical mode. According to the invention, based on the data processing flow described by the protocol, the logic relevance between the setting functions is enhanced, the setting items such as the data stream, the modulation coding scheme and the like in the PPDU generation process are used as the data general setting function and are independently used as a complete setting interface, and the repeated switching is not needed in the setting process, so that the operation convenience is improved.

Description

technical field [0001] The invention belongs to the technical field of network protocols, and in particular relates to a wireless connection physical layer protocol data unit generation device and method. Background technique [0002] Specifications such as IEEE 802.11a / b / g specify the format and definition of the physical layer protocol data unit (PPDU). PPDU generation needs to be carried out according to the protocol, and the logic, availability and convenience of the generating device also need to be considered. The process of PPDU generation is related to many protocol parameters, such as PPDU format, transmission mode, MAC frame type, modulation and coding scheme, bit rate, scrambling mode, etc. The signal generation mode can be divided into frame mode and frameless mode. Each mode has a series of parameter setting methods, which affect the PPDU generation process in their respective modes. [0003] At present, the wireless connection PPDU generating device is usuall...
