A cognitive perspective for information processing in bandwidth-limited wireless communications

摘要

The demands for wireless network bandwidth are rapidly increasing with the expanding number of mobile users as well as the diversification in types of services. Although fast-developing communication techniques continue to enlarge the network capacity, the growth rate of the huge amount of users' demands still outstrip the gains. Learning from the information cognition process of human brains, we introduce new methods to exploit priori information in wireless communications, uncovering a promising area of research in data compression. We showcase the video conversation afforded by such techniques as an example of multimedia communication and propose a modelbased video coding scheme to improve the coding efficiency. Experiment results show that, compared to the conventional video compression codecs, the proposed scheme significantly reduce the data rate while guaranteeing high quality video transmission.
