Abstract

The invention relates to a multi-objective optimization design method based on an effective area. A bacterial foraging algorithm is adopted to take a communication system optimization design objective function as an adaptive value of bacterial tending movement to perform joint optimization on a plurality of design objectives of a communication system. The bacteria swim to the global optimal position in the set effective area by using the self-adaptive step length and direction, meanwhile, the flora is continuously updated by adopting the dynamic retention proportion, and finally, the optimal design scheme of the system is obtained by finding out the optimal regulation and solution of the flora. In order to ensure that the multi-objective optimal optimization design scheme of the system is in the effective area of the system, the effective area is introduced in the process that bacteria tend to move. According to the method, the bacteria can be globally optimal quickly through the self-adaptive step length and direction, so that the problem of complex multi-objective optimization design faced by the design of a communication system is effectively solved.

Description

technical field [0001] The invention relates to the field of communication system design, in particular to a multi-objective optimal design method for a cognitive communication system. In order to overcome the shortcomings of the prior art above, the present invention proposes a multi-objective optimal design method based on effective area. The design method can ensure that the optimized Pareto optimal solution set is in the effective area of ​​the system, and the convergence speed is fast, which effectively solves the complex multi-objective optimization problem faced by the current communication system design. Background technique [0002] my country has a vast territory, complex geographical and climatic conditions, and is one of the countries most severely affected by natural disasters in the world. Building a stable and reliable emergency communication system in time is the primary condition for effectively implementing on-site rescue of major natural disasters. Conve...
