Today's wireless communications systems employ the latest digital modulation and multiple access techniques. Many standards have evolved to spur commercial applications.
These courses focus on CDMA/OFDM fundamentals as well as the techniques that have been incorporated into 5G/4G LTE/Advanced specifications. Topics covered include 5G Wireless Networks, mm-Wave Antennas, Smartphone Architecture, and more.
This video describes the types of problems that fifth generation (5G) cellular systems are seeking to solve, such as the expansion of services to cover diverse needs of the "Internet of Things" and autonomous vehicles.
This tutorial article provides a comprehensive overview of the various 802.11 WiFi standards.
This tutorial provides a brief overview of the Bluetooth specifications and the services that can be provided. It is a good starting point to learn about Bluetooth.
This tutorial article provides an in-depth overview of the Bluetooth protocol. Details such as the various profiles and connection types are covered.
Tutorial on MIMO (multiple input/multiple output) techniques and how they differ from other multiple access strategies. Charan Langton's tutorials are excellent resources for learning complex communications concepts. The bibliography at the end provides a good starting point for further research as well.
This app note gives an overview of the physical layer (radio) aspects of Long Term Evolution (LTE) plans for cellular systems. It provides a good summary of the important concepts.
This in-depth resource provides comprehensive coverage of femtocells and how they integrate with existing 3G and emerging wireless protocols and standards. Femtocells: Design & Application provides a technical roadmap for migrating to femtocell technology, covering network architecture, media protocols, system performance, and security issues. Detailed architectural diagrams illustrate various deployment options. This is a practical guide to the pioneering technology that enables extended indoor service coverage.
This book presents the latest details on LTE from a practical and technical perspective. Written by Agilent's measurement experts, it offers a valuable insight into LTE technology and its design and test challenges. Chapters cover the upper layer signaling and system architecture evolution (SAE). Basic concepts such as MIMO and SC-FDMA, the new uplink modulation scheme, are introduced and explained, and the authors look into the challenges of verifying the designs of the receivers, transmitters and protocols of LTE systems.
Until now, the focus in developing wireless communications formats has been almost exclusively on using novel techniques to overcome specific channel impairments (i.e. multipath, selective fading, etc). What has been missing is an assessment of the overall energy efficiency of the final hardware that is to be deployed. This paper introduces this type of analysis.
