Abstract

A method of wirelessly communicating includes generating, at a wireless device, a packet including a first preamble field. The method further includes generating a first repeated preamble field by multiplying the first preamble field by a first frequency-domain polarity sequence. The method further includes transmitting the packet from the wireless device. The packet includes the first preamble field and the first repeated preamble field.

Description

technical field [0001] In general, certain aspects of the present disclosure relate to wireless communications, and more particularly, to methods and apparatus for detection of communications in wireless networks. Background technique [0002] In many telecommunications systems, a communication network is used to exchange messages between several interacting, spatially separated devices. Networks may be categorized according to geographic extent (eg, it may be a metropolitan area, a local area, or a personal area). Such a network may be designated as a Wide Area Network (WAN), Metropolitan Area Network (MAN), Local Area Network (LAN) or Personal Area Network (PAN), respectively. It is also based on the switching / routing technology used to interconnect the various network nodes and devices (e.g., circuit switching versus packet switching), the type of physical medium used for transmission (e.g., wired versus wireless), and the set of communication protocols used ( For examp...
