On the Optimal Feedback Rate in Interference-Limited Multi-Antenna Cellular Systems
Jeonghun Park, Namyoon Lee, Jeffrey G. Andrews +1
We consider a downlink cellular network where multi-antenna base stations (BSs) transmit data to single-antenna users by using one of two linear precoding methods with limited feed…
MAP Support Detection for Greedy Sparse Signal Recovery Algorithms in Compressive Sensing
Namyoon Lee
A reliable support detection is essential for a greedy algorithm to reconstruct a sparse signal accurately from compressed and noisy measurements. This paper proposes a novel suppo…
Retrospective Interference Alignment for Two-Cell Uplink MIMO Cellular Networks with Delayed CSIT
Wonjae Shin, Yonghee Han, Jungwoo Lee +2
In this paper, we propose a new retrospective interference alignment for two-cell multiple-input multiple-output (MIMO) interfering multiple access channels (IMAC) with the delayed…
Cooperative Base Station Coloring for Pair-wise Multi-Cell Coordination
Jeonghun Park, Namyoon Lee, Robert W. Heath
This paper proposes a method for designing BS clusters and cluster patterns for pair-wise BS coordination. The key idea is that each BS cluster is formed by using the 2nd-order Vor…
Advanced Interference Management Technique: Potentials and Limitations
Namyoon Lee, Robert W. Heath
Interference management has the potential to improve spectrum efficiency in current and next generation wireless systems (e.g. 3GPP LTE and IEEE 802.11). Recently, new paradigms fo…
