In this paper, a new family of one-dimensional (1-D) spreading codes is proposed and constructed by utilizing a one-to-one correspondence algorithm, which can convert the existing two-dimensional (2-D) codes into 1-D codes systematically. The coding method not only improves the encoding efficiency and complexity but also lessens the disadvantage of not generating 1-D spreading codes easily. In addition...
This paper studies the QoS classification problem in the electric power communication networks. A new QoS classification optimization algorithm is proposed based on the mixed artificial fish swarm algorithm, by considering energy efficiency. Firstly, a QoS classification optimization network model is built. The network delay and package loss ratio about the network model is described. Secondly, because...
Mobile advertising is growing faster than any other part of the advertising business. As mobile users and time spent on mobiles devices grow, most advertisements will soon be served on mobile devices. Advertisers are turning to geospatial data to target users, because it provides a unique way of identifying and targeting users beyond the data available on typical desktop devices. Advertising networks...
H.264/AVC is a high performance video coding standard with higher compression and better network compatibility, which not only has important theoretical value but also shows wild application prospect. In order to reduce its computational complexity and achieve real-time application requirements, a multi-stage fast intra mode decision algorithm is proposed. In the first stage, we choose the optimal...
Many existing car recognition algorithms are aiming at front/back and side view car detection. In this paper, an oblique car recognition algorithm is proposed. The algorithm is designed based on the common knowledge of the car, such as shape, contour, structure and so on. The experimental results of many oblique car images show that our method has fine accuracy in oblique car recognition.
