This three-day course provides a working knowledge of modern voice, data and video telecommunication systems. The course is designed for engineers, scientists and managers who wish to enhance their understanding of telecommunications or become familiar with major systems engineering and cost trade-offs and issues.
The course provides the analytical fundamentals and trade-off strategies of modern telecommunications signal processing. The topics are illustrated with worked examples and case studies including echo cancelers, echo suppressors, adaptive filters, FIR and IIR filters and speech processing. The integration of commercial COTS systems into military systems will be discussed.
What you will learn:
This course will provide you with a working knowledge of telecommunications systems and the ability to understand the technical and cost trade-offs with upgrading existing systems and designing new systems.
