A key to spectrum efficiency is the channel assignment problem (CAP), where frequency channels must be assigned to transmitters while minimizing bandwidth and keeping interference at acceptable levels. A method for obtaining lower bounds for the CAP is presented, which is based on representation of channel assignment as a tour through the network. It is shown how bounds can be generated in a systematic way using polyhedral theory, or obtained computationally using linear programming. Bounds and applications of these bounds to a number of specific instances are given as examples |
