—Scarcity of the spectrum resource and mobility of users make Quality-of-Service (QoS) provision a critical issue in wireless networks. This paper presents a fuzzy call admission control scheme to meet the requirement of the QoS. It searches automatically the optimal number of the guard channels in a base station to make an effective use of resource and… (More)
—In this paper, a new PRN code optimal design based on unequal-length code modulation is proposed. The better performance of code acquisition in weak signals will be achieved by using this method, because the cross-correlations between different signals have been sliding, thus suppressing multiple access interference effectively. Theoretical analysis and… (More)
