Abstract: This tutorial paper addresses the physical layer security concerns and resiliency of Orthogonal Frequency Division Multiplexing (OFDM) communications; the de facto air-interface of most ...

Mixers are a fundamental component of wireless communications, and their design constraints become increasingly stringent with the demands of next-generation systems such as 5G and 6G. To meet these ...

Abstract: Integrated sensing and communication (ISAC) is one of the key usage scenarios for future sixth-generation (6G) mobile communication networks, where communication and sensing (C&S) services ...

This paper analyzes the channel estimation of rate splitting multiple access (RSMA) wireless network through the full-duplex amplify-and-forward (AF) relay. Basically, full-duplex transmission can ...

Next generation wireless networks are expected to provide much higher data throughput and reliable connections for a far larger number of wireless service subscribers and machine-type nodes, which ...

We present in this paper a method for enhancing equalization of a dynamic channel. A dynamic channel is characterized and modeled by a high relative velocity between transmitter and receiver and fast ...

THE BIG ISLAND—The ATSC 3.0 standard is nearing completion. Candidate standards have been released for system discovery, or “bootstrap,” and the physical layer. Broadcast engineers will have to ...
