Designing a Robust Carrier Frequency Offset Estimation Scheme for Meeting Target Decoding Performance in an OFDM System
Minkyeong Jeong, Sang-Won Choi, Juyeop Kim
In a target communication system, a delicately designed frequency offset estimation scheme is required to meet certain decoding performance. In this paper, we proposed at wo-step e…
Group Communication Over LTE : A Radio Access Perspective
Juyeop Kim, Sang Won Choi, Won-Yong Shin +2
Long Term Evolution (LTE), which has its root on commercial mobile communications, recently becomes an influential solution to future public safety communications. To verify the fe…
Optimal Multiplexing Gain of K-user Line-of-Sight Interference Channels with Polarization
Sung ho Chae, Sang Won Choi, Sae-Young Chung
We consider the multiplexing gain (MUXG) of the fully connected K-user line-of-sight (LOS) interference channels (ICs). A polarimetric antenna composed of 3 orthogonal electric dip…
On the Beamforming Design for Efficient Interference Alignment
Sang Won Choi, Syed A. Jafar, Sae-Young Chung
An efficient interference alignment (IA) scheme is developed for -user single-input single-output frequency selective fading interference channels. The main idea is to steer the…
On the Separability of Parallel Gaussian Interference Channels
Sang Won Choi, Sae-Young Chung
The separability in parallel Gaussian interference channels (PGICs) is studied in this paper. We generalize the separability results in one-sided PGICs (OPGICs) by Sung \emph{et al…
