Embodiment Construction
[0040] Taking the millimeter wave wireless local area network (IEEE802.11aj) as an example below, the present invention is further illustrated in conjunction with the accompanying drawings. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. After reading the present invention, this Modifications to various equivalent forms of the present invention by those skilled in the art fall within the scope defined by the appended claims of the present application.
[0041] In the field of wireless communication, the frame synchronization detection algorithm based on ZCZ sequence has various applications. For example, it is used for frame detection and synchronization. At this time, it is often necessary to send multiple repeated ZCZ sequences on the antenna, and use multiple correlation operations for detection.
[0042] In the embodiment of the present invention, the single-c...
