Event-Driven Optimal Feedback Control for Multi-Antenna Beamforming
Kaibin Huang, Vincent K. N. Lau, Dongku Kim
Transmit beamforming is a simple multi-antenna technique for increasing throughput and the transmission range of a wireless communication system. The required feedback of channel s…
Delay-Sensitive Distributed Power and Transmission Threshold Control for S-ALOHA Network with Finite State Markov Fading Channels
Huang Huang, Vincent K. N. Lau
In this paper, we consider the delay-sensitive power and transmission threshold control design in S-ALOHA network with FSMC fading channels. The random access system consists of an…
A Low-Overhead Energy Detection Based Cooperative Sensing Protocol for Cognitive Radio Systems
Shunqing Zhang, Tianyu Wu, Vincent K. N. Lau
Cognitive radio and dynamic spectrum access represent a new paradigm shift in more effective use of limited radio spectrum. One core component behind dynamic spectrum access is the…
A New Scaling Law on Throughput and Delay Performance of Wireless Mobile Relay Networks over Parallel Fading Channels
Rui Wang, Vincent K. N. Lau, Kaibin Huang
In this paper, utilizing the relay buffers, we propose an opportunistic decode-wait-and-forward relay scheme for a point-to-point communication system with a half-duplexing relay n…
Delay-Optimal Power and Precoder Adaptation for Multi-stream MIMO Systems
Vincent K. N. Lau, Yan Chen
In this paper, we consider delay-optimal MIMO precoder and power allocation design for a MIMO Link in wireless fading channels. There are data streams spatially multiplexed ont…
Cross-Layer Design of FDD-OFDM Systems based on ACK/NAK Feedbacks
Zuleita Ka Ming Ho, Vincent K. N. Lau, Roger S. K. Cheng
It is well-known that cross-layer scheduling which adapts power, rate and user allocation can achieve significant gain on system capacity. However, conventional cross-layer designs…
