Wireless communication systems to date primarily rely on the orthogonality of resources to
facilitate the design and implementation, from user access to data transmission. Emerging …

In this work, we thoroughly analyze the rate-region provided by the asynchronous
transmission in multiple access channels (MACs). We derive the corresponding capacity …

Two-user non-orthogonal multiple access systems with quadrature phase-shift keying
modulation are studied. A time asynchronous scheme for successive interference …

We investigate multiuser detection under uplink asynchronous scenario, where the
triangular successive interference cancellation (T-SIC) detection scheme is exploited. As the …

The next-generation multiple access (NGMA) serves as an umbrella term encompassing
transmission schemes distinct from conventional orthogonal methods. As a prominent …

This letter proposes a novel time-asynchronous non-orthogonal multiple access (TA-NOMA)
in downlink multicarrier systems. TA-NOMA applies an intentional time offset to control …

Low Earth orbit (LEO) satellite networks will become the core infrastructure of space–air–
ground integrated networks in 6G wireless technology, providing ubiquitous broadband …

Ultra-dense low-Earth-orbit (LEO) networks will integrate with terrestrial networks and play
an important role in the future 6G. However, the reused frequency resource leads to serious …

In this letter, we study a two-user downlink asynchronous non-orthogonal multiple access
(ANOMA) with limited feedback. We employ the max-min criterion for the power allocation …

Non-orthogonal multiple access (NOMA) is a key technology for future wireless access.
Recently, asynchronous NOMA (ANOMA) has attracted attention due to its large achievable …
