Selection of intermodulation-free frequencies for multiple-channel mobile radio systems
Rodger E. Edwards, John R. Durkin, D.H. Green · Proceedings of the Institution of Electrical Engineers · 1969
The paper presents results which enable the designer of a mobile radio network to allocate channel frequencies which give freedom from interfering third- or fifth-order intermodulation products. The general rules for the selection of third- and fifth-order mutually compatible channels are developed, and Tables of channel-difference sequences are presented for direct use in channel allocation. An extension of the theory for immunity to higher-order products is also given.
