Computation of single-tone spurious effects in radio communication systems

摘要

A semiempirical computational method for obtaining a list of forbidden, potentially disturbing, single-tone spurious frequencies for each receiver system operating channel is described. A UHF/FM radio communication system, including two frequency converter stages, is used to demonstrate the method's ability to improve system performance. The forbidden list is shown to be a very useful tool for improving system frequency interference immunity during the initial stages of system design and for improving frequency allocation. This method can be applied to systems operating in various frequency ranges and using different modulation methods.
