With the rapid progress of 3GPP LTE/LTE-A's standardization, research about coordinate multi point reception / transmission (CoMP) is very popular. However, topics about CoMP were freezed in around 2009 by 3GPP, so further research and performance analysis about key techniques in CoMP is very little. In this paper, we studied the dynamic cell selection method which is presented in some proposals [1],...
In cognitive radio networks (CRN), underlay spectrum sharing allows secondary users (SUs) to utilize the spectrum on which the primary users (PUs) in primary radio networks (PRN) are working at the same time, without introducing intolerant interferences. In this paper, we study the joint transmission power and time allocation in CRN with underlay spectrum sharing technology. To maximize the total...
In the RoboCup soccer humanoid league competition, the vision system is used to collect various environment information as the terminal data to finish the functions of object recognition, coordinate establishment, robot localization, robot tactic, barrier avoiding, etc. Thus, a real-time object recognition and high accurate self-localization system of the soccer robot becomes the key technology to...
