Cohere Technologies was awarded a $28 million contract by the Department of Defense (DoD) to develop radio access network (RAN) technologies to advance 5G/6G infrastructure. The contract will support ...

The development of the 6G standard is entering a more concrete phase. At the June 2026 3GPP RAN Plenary in Singapore, the industry advanced several key areas under study and finalized the timeline for ...

Abstract: A number of inherently unipolar orthogonal frequency division multiplexing (OFDM) modulation schemes have been introduced recently in an attempt to improve the energy efficiency of ...

Abstract: In this paper, we explore design aspects of adaptive modulation based on orthogonal frequency-division multiplexing (OFDM) for underwater acoustic (UWA) communications, and study its ...

Orthogonal time frequency and space (OTFS) modulation is a promising technology that satisfies high Doppler requirements for future mobile systems. OTFS modulation encodes information symbols and ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

This paper presents an evaluation of multicarrier channel sounding techniques using different random and pseudo-random sequences to modulate the OFDM sounding signal. The Random (Rand), Pseudo-Noise ...

Seeed Studio has launched two 900 MHz WiFi HaLow modules for long-range, low-power communication based on Quectel FGH100M-H: the Wio-WM6180 Wi-Fi HaLow mini-PCIe module designed to be installed in ...

A high security physical layer encryption scheme for dual-mode orthogonal frequency division multiplexing with index modulation (DM-OFDM-IM) in magnetic induction communication is proposed. The scheme ...
