CDMA/TDD system for wireless multimedia services with traffic unbalance between uplink and downlink
Dong Geun Jeong,Wha Sook Jeon +1 more
TL;DR: In this article, the authors proposed a code division multiple access (CDMA) time division duplex (TDD) system for wireless multimedia services with traffic unbalance between uplink and downlink.
Journal ArticleDOI
Performance of an exponential backoff scheme for slotted-ALOHA protocol in local wireless environment
Dong Geun Jeong,Wha Sook Jeon +1 more
TL;DR: The paper suggests a very simple backoff scheme for slotted ALOHA and evaluates its performance in local wireless environments and gives a protocol parameter value which is highly recommendable from the practical viewpoint.
Journal ArticleDOI
Call admission control for CDMA mobile communications systems supporting multimedia services
Wha Sook Jeon,Dong Geun Jeong +1 more
TL;DR: The proposed CAC scheme can operate well in the mobile multimedia systems such as the International Mobile Telecommunications-2000 (IMT-2000) systems and is evaluated using Markov analysis.
Journal ArticleDOI
Energy-Efficient Channel Management Scheme for Cognitive Radio Sensor Networks
TL;DR: A new channel management scheme for CRSNs is proposed, which heightens the energy efficiency while not greatly disturbing a PU, and the simulation results show that the proposed scheme energy-efficiently operates while properly protecting a PU.
Journal ArticleDOI
Comparison of time slot allocation strategies for CDMA/TDD systems
Wha Sook Jeon,Dong Geun Jeong +1 more
TL;DR: This paper investigates a slot allocation strategy (DA strategy), by which each cell has its own slot allocation according to the level of traffic asymmetry, and shows that the system with DA strategy outperforms theSystem with SA strategy in the aspect of capacity.
