Non-blind audio bandwidth extension is a standard technique within contemporary audio codecs to efficiently code audio signals at low bitrates. In existing methods, in most cases high frequencies signal is usually generated by a duplication of the corresponding low frequencies and some parameters of high frequencies. However, the perception quality of coding will significantly degrade if the correlation between high frequencies and low frequencies becomes weak. In this paper, we quantitatively analyse the correlation via computing mutual information value. The analysis results show the correlation also exists in low frequency signal of the context dependent frames besides the current frame. In order to improve the perception quality of coding, we propose a novel method of high frequency coarse spectrum generation to improve the conventional replication method. In the proposed method, the coarse high frequency spectrums are generated by a nonlinear mapping model using deep recurrent neural network. The experiments confirm that the proposed method shows better performance than the reference methods.

Partitioning algorithm for PON network design

2010 The 3rd International Conference on Computational Intelligence and Industrial Application (PACIIA2010)

作者： Weicheng Xiong School of computer Wuhan University Wuhan china Chanle Wu and Libing Wu School of computer Wuhan University Wuhan china Xiaojun Guo Yibo Chen and Ming Xie School of computer Wuhan University Wuhan china

Optical access technology has quickly got a worldwide development. Currently,the deployment of equipment and fiber lines in the optical access network need professionals to design. But,because the lack of a unified standard,it is difficult to make the network reasonable. By analyzing the PON architecture model,this article talks about an improved partitioning algorithm for PON network design. By entering some parameters,it can automatically calculate the number and configuration of OLT,which can help to optimize the network layout,and save the network construction costs.

In pervasive computing, one of the key open challenges is the efficient discovery of the device that provides target services. This paper proposes a novel distributed service discovery algorithm in pervasive computing environments. This method is based on the basic principle of social network and bio-inspired intelligence. It exploits a social behavior and ant inspired query routing mechanism, which views query messages as artificial ants, and utilizes pheromone and social utility as routing hints that direct query messages to nodes owning more services. This paper presents generation and update rule of pheromone, routing policy for artificial ants as well. In order to avoid getting into local optimization, the roulette wheel technique and pheromone limitation policy are used in our algorithm. Simulation results show that our method significantly improves the search quality as well as reduces traffic cost compared with classical approaches, which supports high mobility and is suitable for pervasive environments.
