ABSTRACT
Sectorized antennas provide an attractive solution to increase wireless network capacity through interference mitigation. Despite their increasing popularity, the real-world performance characteristics of such antennas in dense wireless mesh networks are not well understood. We demonstrate our multi-sector antenna prototypes and their performance through video streaming over an indoor wireless network in the presence of interfering nodes. We use our graphical tool to vary the sender, receiver, and interferer antenna configurations and the resulting performance is directly visible in the video quality displayed at the receiver.

Cochannel interference mitigation using whitening receiver designs in bandlimited microcellular wireless systems
The problem of cochannel interference (CCI) suppression using a noise-plus-interference whitening matched filter (WMF) is addressed. Binary phase-shift keying modulated transmission over a Nakagami-m fading channel is considered in a bandlimited ...

Block Diagonalization for Inter-cell Interference Mitigation with Limited CSI Feedback
ICCECT '13: Proceedings of the 2013 International Conference on Control Engineering and Communication TechnologyBlock diagonalization (BD) as a low complexity MIMO technique has been considered for inter-cell interference mitigation based on the perfect channel state information (CSI) in many previous works. However, the imperfect CSI feedback is more practical ...
