A bound on the relationship between intermodulation noise and carrier frequency assignment

This paper describes the relationship between third-order intermodulation products and assigned bandwidth. A lower bound of the third-order intermodulation products falling into signal channels is derived using the concept of difference triangular sets. In addition, solutions of the intermodulation/minimum frequency assignment sequence are given for practical applications. A comparison of such optimum solutions with the lower bound derived in this paper indicates that the latter is useful for evaluating the relationship between the utilization efficiency of the assigned bandwidth and the intermodulation impairment level.
