Background Next-generation wireless networks in beyond-5G and 6G face critical challenges in meeting increasing demands for fast data rates and strict requirements on mobility, reliability, latency, and energy efficiency. Current approaches to satisfy the data rate requirements include using high-frequency bands in millimeter wave (mmWave) and sub-terahertz,...

Background Millimeter-wave (mmWave) and terahertz (THz) frequency bands are growing in prevalence in current and future communication systems. These frequency ranges provide higher bandwidths, which enable the communication systems to efficiently meet the higher data requirements of high speed applications including augmented or virtual reality, autonomous...

Background Mastering a language involves not only learning new alphabets and expanding vocabulary, but also mastering sentence construction, pronunciation, and effectively engaging in listening, speaking, reading, and writing activities. Each aspect presents unique challenges for learners, especially non-native speakers. Traditional methods of language...

­Background Recent years have seen a growing interest in systems and technologies that rely on vision and wireless systems to provide certain capabilities. Examples include vision-aided wireless communications and wireless-vision activity recognition. However, these technologies have a common shortcoming; they do not directly address the association...
