In this paper BP network was improved based on the Double Chains Quantum Genetic Algorithm (DCQGA). The predicted model of laser bending angle based on our proposed BPN-DCQGA network was set up in the process of sheet metal laser bending. The BPN-DCQGA network was trained and verified through the sample data result from experimental data, and it is proved that our proposed network has enhanced the...
MIMO OFDM systems are applied in IEEE 802.11n wireless communication standard for improvement of transmission ability. In MIMO OFDM systems, to recover mixed source signals in receivers is one of significant objectives. Blind signal separation (BSS) techniques are such suitable methods to separate linearly mixed independent source signals given only observations in receivers of MIMO OFDM systems....
In order to reduce registration time, improve convergence ability and perform better in the presence of noise, a novel medical image registration measure is proposed, which is called generalized Jensen-Schur measure. According to Jensen-Schur measure, two kinds of special measures are constructed: Jensen-Schur- alpha and Jensen-Rényi-alpha. The characters of the two measures, mutual information and...
