Intelligent signal processing for wireless communications is a vital task in modern wireless systems, but it faces new challenges because of network heterogeneity, diverse service requirements, a massive number of connections, and various radio characteristics. Owing to recent advancements in big data and computing technologies, artificial intelligence (AI) has become a useful tool for radio signal processing and has enabled the realization of intelligent radio signal processing. This survey covers four intelligent signal processing topics for the wireless physical layer, including modulation classification, signal detection, beamforming, and channel estimation. In particular, each theme is presented in a dedicated section, starting with the most fundamental principles, followed by a review of up-to-date studies and a summary. To provide the necessary background, we first present a brief overview of AI techniques such as machine learning, deep learning, and federated learning. Finally, we highlight a number of research challenges and future directions in the area of intelligent radio signal processing. We expect this survey to be a good source of information for anyone interested in intelligent radio signal processing, and the perspectives we provide therein will stimulate many more novel ideas and contributions in the future.

Currently, it is able to identify species in North America and Europe and, with the power of ultra-fast Verizon 5G, the number of birds and other animals it can recognize will continue to grow.Watch the futuristic gadget in action in the video above.If you enjoyed this article, check out the Hollywood sci-fi technology …

Qualcomm, a leader in wireless technology, has recently released the world's first 5G and AI-enabled robotics platform. Qualcomm says the Robotics RB5 platform includes novel technology that will accelerate the development of power-efficient, high-computing robots and drones for applications ranging from industrial and enterprise applications to defense and military sectors. Specifically, some of the applications this platform can enhance include inventory robots, retail robots, pick-sort-place robots, cleaning robots, delivery drones, healthcare robots, and defense robots. Qualcomm's Robotics RB5 platform, punctuated by their QRB5165 processor, supports a number of connectivity protocols through Qualcomm's FastConnect subsystems: Wi-Fi 6, Bluetooth 5.1, 4G, and 5G. This platform has been designed specifically for applications in robotics, and it comes with hardware, software, and other development tools to help designers with such applications.

Google today announced the launch of an OpenCL-based mobile GPU inference engine for its TensorFlow framework on Android. It's available now in the latest version of the TensorFlow Lite library, and the company claims it offers a two times speedup over the existing OpenGL backend with "reasonably-sized" AI models. OpenGL, which is nearly three decades old, is a platform-agnostic API for rendering 2D and 3D vector graphics. Compute shaders were added with OpenGL ES 3.1, but the TensorFlow team says backward-compatible design decisions limited them from reaching device GPUs' full potential. On the other hand, OpenCL was designed for computation with various accelerators from the beginning, and was thus more relevant to the domain of mobile GPU inference.

Communications technology reached a historic milestone at the beginning of April this year as Hong Kong's fifth-generation mobile (5G) network was officially fully connected, linking all major communication equipment. A 5G network provides much more than just increased bandwidth and speed – 5G provides the opportunity to deploy artificial intelligence (AI) technology to bring the much-discussed Internet of Things (IoT) out of the laboratory and into the real world. To give people from all walks of life a better understanding of 5G networks, the Hong Kong Trade Development Council (HKTDC) held the Tech Trends Symposium 2020 – The Future of Intelligent Connectivity on 28 July. Forming part of the HKTDC's Summer Sourcing Weeks Go ONLINE virtual trade fair (27 July-7 August), the symposium was streamed online. At a session titled "Empowering a Connected Future with 5G", industry leaders introduced the latest developments in 5G networks and expressed the hope that Hong Kong will keep pace with the world in moving towards 5G and building a smart city.

Networks can describe the structure of a wide variety of complex systems by specifying how pairs of nodes interact. This choice of representation is flexible, but not necessarily appropriate when joint interactions between groups of nodes are needed to explain empirical phenomena. Networks remain the de facto standard, however, as relational datasets often fail to include higher-order interactions. Here, we introduce a Bayesian approach to reconstruct these missing higher-order interactions, from pairwise network data. Our method is based on the principle of parsimony and only includes higher-order structures when there is sufficient statistical evidence for them.

We begin with Mr Rashid Oukhai, the Founder and CEO of Peculium. A student of computer sciences, Rashid began his journey some 20 odd years back when Big Data was not formally called so. His interest in data sciences ripened when he started working with a well known Telecommunications provider in France. His first task on his first day was to make sense of a massive database! For most of us, that would have been a daunting task. However, there are few among us that love to work with data.

AWS announced the general availability of AWS Wavelength on Verizon's 5G Network. Applications demanding ultra-low latency in single-digit milliseconds can leverage AWS compute and storage at the edge with Verizon's 5G Network. The service is now available with Boston and the San Francisco Bay, starting with the San Jose area. AWS has embedded AWS compute and storage services at the edge of 5G with Verizon's 5G Network. Developers can now leverage machine learning, Internet of Things (IoT), and video/game streaming requiring low latency edge processing with AWS Wavelength, notes the announcement.
