Wideband FDM/FM Microwave Radio Relay Performance Degradation Investigation.

reportActive / Technical Report | Accession Number: ADA068757 | Open PDF

Abstract:

A general investigation of the performance degradation in FDMFM systems when exposed to various types of interference signals was made through a combined use of detailed measurements and analyses. Several techniques are described for evaluating the performance degradation in FDMFM systems. These techniques use a combination of measured data and engineering trends covering a reasonably complete range of receiver and interference parameters. The measurement methodology is also documented. Author
