The Future of Communications

The essence of communication is the imparting or exchanging of information. We can broadly define three primary types of communication personal, media, and control type communication, each of which results in the exchange of information between people or systems. Personal communication can be regarded as the exchange of information or perspective with one or more people; media-type communication occurs when a system exchanges content with a person or another system; and control-type communication occurs when a person exchanges commands or information to from a device or system. A single communication session can be comprised of more than one of these types, but the goal of unified communications has remained elusive as different and often proprietary protocols and encapsulations of information and content have been used and persist due both to their ubiquity as well as the security or protections they provide. But increasingly, the boundaries between these modes of interaction are blurring as new IP-based protocols and message handling schemes allow communication of content, information or commands by and with people, systems and devices. Consequently, in the future we believe that a new communications paradigm will emerge driving an era of truly unified communications, with anyone or anything is accessible by anyone or anything. This will profoundly change how we interact and will drive a new digital existence, in which we are always connected and can communicate with any system, or device, or person, allowing continuous and perpetual augmentation of our lives.

Fair Dynamic Spectrum Management for QRD-Based Precoding with User Encoding Ordering in Downstream Transmission

In next generation DSL networks such as, employing discrete multi-tone transmission in high frequencies up to 212 MHz, the crosstalk among lines reaches very high levels. To precompensate the crosstalk in downstream transmission, QRD-based precoding has been proposed as a near-optimal dynamic spectrum management (DSM) technique. However, the performance ...

Practical Mitigation of Passive Intermodulation in Microstrip Circuits

This paper presents new experimental evidence and a novel practical approach for mitigation of passive intermodulation (PIM) in microstrip circuits fabricated on commercial printed circuit board laminates. The mechanisms of distributed PIM in microstrip circuits are reviewed and a phenomenology of PIM generation due to locally enhanced electromagnetic fields at ...

Efficient Cooperative HARQ for Multi-Source Multi-Relay Wireless Networks

In this paper, we compare the performance of three different cooperative Hybrid Automatic Repeat reQuest (HARQ) protocols for slow-fading half-duplex orthogonal multiple access multiple relay channel. Channel State Information (CSI) is available at the receiving side of each link only. Time Division Multiplexing is assumed, where each orthogonal transmission occurs ...
