Improving Spectrum Use While Maintaining Legacy Compatibility
Edward M. Valovage · Institution of Engineering and Technology eBooks · 2011
As the demand grows for RF communication of information, the technologists will have to contend with existing systems, procedures, equipment, and allocated communication bands. In a few cases, new systems can be developed without legacy constraints. But in many cases, new capability must be added to existing systems in existing allocated bandwidth, and must allow continued operation of the existing equipment. This poses challenges to the system designer requiring clever engineering innovation in addition to mathematical principles of optimum communication of information.
