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...
The GSM wireless network coverage is one of the important factors that affect the service quality of the wireless network. With the ever-changing network broadcasting environment (network communication environment), in view of the problems that the spreading path loss and signal attenuation become more and more serious, the paper discusses the hata model and its application conditions, and adopting...
