Abstract: This paper studies enhanced physical-layer key generation (PKG) for multiuser orthogonal frequency division multiple access (OFDMA) networks. In practical OFDMA systems, our key observation ...

Analog radio broadcasts are pretty simple, right? Tune into a given frequency on the AM or FM bands, and what you hear is what you get. Or at least, that used to be the way, before smart engineers ...

Wi-Fi 7 (802.11be) routers and modules have only been launched recently, but engineers are already working on Wi-Fi 8 (802.11bn) “Ultra High Reliability (UHR)”, and MediaTek shared some details in a ...

Wi-Fi 7, or 802.11be, was only certified in January and its adoption is just beginning to ramp up; however, whispers of Wi-Fi 8, or 802.11bn, are beginning to circulate, with some of its technical ...

Abstract: Index Modulation based Orthogonal Frequency Division Multiple Access (IM-OFDMA) is an uplink scheme that allows a set of users to share a chunk of frequency subcarriers by the means of IM.

Signal modulation identification is of high interest for applications in military communications, but is not limited only to this specific field. Some possible applications are related to spectrum ...

I am researching channel quality estimation using channel state information. So have a question about the pilot subcarrier. pilot subcarrier is known as periodically transmitting subcarriers with the ...
