Abstract
Quantum intelligence algorithm, as the combination of the quantum computing theory and the principle of intelligence algorithm, is a new global optimization algorithm, which has the characteristics of smaller population size, stronger capability in the optimization, faster convergence and shorter time in computing. It has already been widely used in many areas.The OFDM resource allocation plays an important part in OFDM system,it can acquire the least transmittion power and minimize the BER.
This paper focus on the quantum genetic algorithm and its application on OFDM resource allocation. At first it brings out the quantum genetic algorithm and its improved algorithm,then apply the algorithm on OFDM multi-user adaptive modulation.This methods can solve the conflict subcarrier effectively.which can be verified on computer simulation.
This paper also describes the quantum immune algorithm,find a better way to access to vaccine and vaccination,which can solve the 0-1 knapsack problem in a high efficiency.in the end it apply the improved quantum immune algorithm on the OFDM single-user modulation,compare to the claasic modulation algorithm,it can get a good BER performance and a fast convergence result.
