Assignment of Frequency Lists in Frequency Hopping Networks
IEEE Transactions on Vehicular Technology, 2005Metaheuristic algorithms for frequency assignment problems have received considerable attention in the literature, but few papers have addressed the question of list assignment in frequency hopping networks. The work of Bjo/spl uml/rklund, Va/spl uml/rbrand, and Yuan is a notable exception, which will be extended here in a number of directions.

Optimization of frequency assignment
IEEE Transactions on Communications, 1989A systematic method of determining carrier frequency assignment is proposed to minimize the cochannel interference in satellite communication systems. For the mathematical treatment of the problem, discrete positioning of carriers is introduced to avoid the nonlinear expression inherent in interference evaluation.

Radio Link Frequency Assignment
Constraints, 1999The problem of radio frequency assignment is to provide communication channels from limited spectral resources whilst keeping to a minimum the interference suffered by those whishing to communicate in a given radio communication network. This problem is a combinatorial (NP-hard) optimization problem.

Frequency Assignment for JALN HCB
2018 IEEE 39th Sarnoff Symposium, 2018Joint Aerial Layered Network (JALN) could provide crucial communication links when milsatcoms are degraded or lost. Antenna assignment problem for JALN High Capacity Backbone (HCB) has been studied in [1], [2] where each JALN aircraft has four mounting points for directional antennas.

The Application of Frequency Assignment Techniques in Spreading Code Assignment
Wireless Personal Communications, 2009The use of spreading codes with a zero correlation zone or a low correlation zone can reduce multiple access interference in code-division multiple-access (CDMA) radio systems. However, problems can arise from the limited number of codewords. In this paper it is shown that this shortage of codewords can be mitigated by a combination of two approaches ...

Presents a new assignment method which has been developed by the author and has been used since the end of 1992 for the design of the frequency plan of the German GSM-Network D1 operated by the DeTeMobil. The new method aims to optimize the interference situation in cellular radio networks under the main constraint of satisfying the frequency demand of

IEEE Transactions on Electromagnetic Compatibility, 1977
An automated procedure has been developed for use in radar frequency assignment problems. This procedure is based upon the area denial concept. This technique recognizes the fact that receivers, as well as transmitters, deny spectrum space to additional systems being introduced into a given environment.
