CLAASSES OF FREQUENCIES FREE OF MUTUAL INTERFERENCE: A THEORY OF FREQUENCY ASSIGNMENTS,
Abstract
The mutual interference chart (MIC) gives the compatibility that exists between the channels of a radio set. This property of the chart is used to determine classes of frequencies that are compatible with given transmitting or receiving frequencies. The approach is based on the ele mentary theory of classes. The class characterization implies a set of frequency assignments. The general theory for obtaining these assignments is developed. The assignment can be constructed not only to eliminate mutual interference from co-located sources, but also to control co-channel and other interference from distant sources. Analytically, the general theory can be applied without excessive labor only to the simple reentrant circuit of three terminals in the case in which the MIC consists solely of a diagonal swath.
