Abstract

The invention discloses a mobile user spectrum allocation method based on a cuckoo search algorithm. For the problem that in spectrum power allocation, network throughput is low, firstly, awareness based on an interference distance is built, and a spectrum power allocation problem is converted to a function optimization problem; maximized network throughput is converted to solving a total data volume completed in maximization available time, a target function is built, a spectrum allocation available is mapped to a position of a cuckoo nest, the cuckoo search algorithm is adopted for solving,finally, spectrum allocation with the network throughput higher than that of a genetic algorithm is obtained, and high secondary user effective channel capacity can be obtained.

Description

technical field

[0001] The invention relates to the technical field of wireless communication, in particular to a mobile user spectrum allocation method based on a cuckoo search algorithm. Background technique

[0002] Cuckoo search (CUCKOO SERACH) referred to as CS is a new type of intelligent algorithm derived from the parasitic behavior of cuckoo hatching in nature and the principle of levy flight search. It has high performance in exploring the solution space and can flexibly jump out of local extreme values. Moreover, the structure is very simple, the control parameters are less, the adjustment and setting of parameters are convenient, and it is easy to implement. It is widely used in solving nonlinear programming problems. This is a network model in which multiple primary users and multiple secondary users share the same frequency band , under the premise of ensuring the normal communication of the primary user link, by controlling the transmit power of the secondary u...
