Architecting Large Switch Fabrics For Fiber-Optic Systems
By Ian Kyles
In the realm of optical communications, there can never be enough bandwidth. However, communication systems designers can turn to a three-stage switching fabric architecture in order to meet the ever increasing demand.
Carrier Synchronization Techniques For DSP-Based Modems
By Fred Harris
Increased demand for digital modem technology has lead toward a higher demand for DSP-based modem technology. In these designs, engineers can run into problems when extracting information from received signals. Synchronization techniques provide engineers with the ability to overcome these problems.
Building Next-Generation Network Security Processors
By Stephen Davis and Mel Roberts
The call is out for increased security in communication products such as edge access equipment, routers, and cable headend gear. As a result, communication systems designers are being called upon to provide security processing in coprocessors that is not only fast but that is also able to respond to changes in security technologies.
Smart Antenna Schemes For E-911
By Matthew Plonski
The FCC mandate for E-911 functionality is just around the corner. Fortunately, wireless systems designers can combine smart antenna technology with direction-of-arrival algorithms to develop systems enabling accurate location information.
