Multi-user diversity in a spectrum sharing system
TL;DR: The numerical and analytical results show that the multiuser diversity gain in a spectrum sharing system increases differently according to conditions given by the transmit power of secondary users, P, and a predetermined interference temperature, Q.

TL;DR: In this paper, a radio communication system that can minimize power consumption by eliminating a need for carrier detection and sharing transmission/reception time information in UWB impulse communications is presented. But the system is not suitable for ultra wideband (UWB) communications.
Journal ArticleDOI
Opportunistic Interference Alignment for Interference-Limited Cellular TDD Uplink
Bang Chul Jung,Won-Yong Shin +1 more
TL;DR: Simulation results show that the proposed OIA scheme provides significant improvement in terms of sum rates, and does not require global channel state information, time/frequency expansion, and a number of iterations, thereby resulting in easier implementation.
Journal ArticleDOI
Recursive Pseudo-Bayesian Access Class Barring for M2M Communications in LTE Systems
TL;DR: Numerical results show that the proposed Bayesian ACB algorithms yield quite similar performance with the ideal ACB algorithm, assuming that the exact number of active devices is known to the eNodeB.
Journal ArticleDOI
Opportunistic Interference Alignment for MIMO Interfering Multiple-Access Channels
TL;DR: The sum-rate performance of the proposed OIA techniques is compared with the conventional techniques in MIMO IMAC channels and it is shown that the proposedOIA techniques outperform theventional techniques.
