The sixth-generation (6G) network is envisioned to support growing Internet connections
with the requirements of higher transmission rate, higher reliability, lower latency, etc. While …

In the sixth generation (6G) era, intelligent machine network (IMN) applications, such as
intelligent transportation, require collaborative machines with communication, sensing, and …

Channel state information (CSI) estimation is one of the most fundamental problems in
wireless communication systems. Various methods, so far, have been developed to conduct …

We propose a two-stage channel estimation procedure for a multi-antenna base station (BS)
assisted by a reconfigurable intelligent surface (RIS). In Stage 1, the BS estimates the direct …

A low-complexity channel estimation and passive beamforming design for intelligent
reflecting surface (IRS)-assisted multiple-input single-output (MISO) systems is proposed …

Active reconfigurable intelligent surface (ARIS) is a newly emerging RIS technique that
leverages radio frequency (RF) reflection amplifiers to empower phase-configurable …

This paper proposes a wireless channel assessment metric A posteriori Bit Error Probability
(ABEP) that indicates the error likelihood of each bit during demodulation. Estimated upon …

Channel quality indicator (CQI) is a key parameter in communication system design that
encodes the state of the channel. With this information, a base station (BS) can adjust the …

The introduction of adaptive coding and modulation (ACM) in DVB-S2 improves system
capacity. Transmission mode is adapted to receiving conditions which are fed back through …

The Internet of Things is a novel paradigm with access to wireless communication systems
and artificial intelligence technologies, which is considered to be applicable to a variety of …
