Embodiment approach

[0127] In the first optional implementation manner, if the signals carried by the selected two data units are subjected to FFT to obtain the processed signal, then it is judged whether the energy of the even-numbered sub-carriers of the processed signal is much greater than that of the odd-numbered sub-carriers energy, if so, it is determined that the signals carried by the two data units are anti-symmetrical, that is, the target field has an anti-symmetric feature.

[0128] In the second optional implementation manner, if the signals carried by the two first target data units are superimposed to obtain the first processed signal, and the signals carried by the two second target data units are superimposed to obtain the second Two processing signals. Then compare the first processed signal with the second processed signal, if the first processed signal is much smaller than the second processed signal, it means that the signals carried by the two data units are anti-symmetrical...

Abstract

The embodiment of the invention discloses a signal processing method, a sending station and a receiving station. The method comprises the steps that the sending station obtains a target signal for indicating a signal transmission feature and a standard category for packaging the target signal, wherein the standard category comprises a first standard or a second standard; if the standard category is the first standard, the sending station carries out a negation operation on the target signal; the sending station packages the target signal after the negation operation into a preset field of a first standard frame and obtains the first standard frame with a negation feature; and the sending station sends the first standard frame with the negation feature. Through adoption of the method and the stations, the receiving station can identify two standard frames.

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to a signal processing method, a sending station and a receiving station. Background technique [0002] In a 60G high-frequency wireless local area network (Wireless Local Area Network, WIFI), the existing standard is mainly 802.11ad. The standard currently supports a maximum rate of 6.7Gbps. In order to meet higher rate requirements, new technologies and standards need to be introduced. For example, a new standard 802.11ay is currently introduced on the basis of the 802.11ad standard. The introduction of the new standard needs to meet backward compatibility, which mainly includes two points: 1. The equipment corresponding to the new standard can not only connect to the 802.11ad equipment, but 2. At the same time, it will not interfere with the original equipment . In the actual WIFI system, when a device supporting the new standard 802.11ay sends data, the data ...
