On the Number of RF Chains and Phase Shifters, and Scheduling Design with Hybrid Analog-Digital Beamforming
Tadilo Endeshaw Bogale, Long Bao Le, Afshin Haghighat +1
This paper considers hybrid beamforming (HB) for downlink multiuser massive multiple input multiple output (MIMO) systems with frequency selective channels. For this system, first…
Wideband Sensing and Optimization for Cognitive Radio Networks with Noise Variance Uncertainty
Tadilo Endeshaw Bogale, Luc Vandendorpe, Long Bao Le
This paper considers wide-band spectrum sensing and optimization for cognitive radio (CR) networks with noise variance uncertainty. It is assumed that the considered wide-band cont…
Joint Cooperative Spectrum Sensing and MAC Protocol Design for Multi-channel Cognitive Radio Networks
Le Thanh Tan, Long Bao Le
In this paper, we propose a semi-distributed cooperative spectrum sen sing (SDCSS) and channel access framework for multi-channel cognitive radio networks (CRNs). In particular, we…
Sensing Throughput Tradeoff for Cognitive Radio Networks with Noise Variance Uncertainty
Tadilo Endeshaw Bogale, Luc Vandendorpe, Long Bao Le
This paper proposes novel spectrum sensing algorithm, and examines the sensing throughput tradeoff for cognitive radio (CR) networks under noise variance uncertainty. It is assumed…
General analytical framework for cooperative sensing and access trade-off optimization
Le Thanh Tan, Long Bao Le
In this paper, we investigate the joint cooperative spectrum sensing and access design problem for multi-channel cognitive radio networks. A general heterogeneous setting is consid…
Channel assignment for throughput maximization in cognitive radio networks
Le Thanh Tan, Long Bao Le
In this paper, we consider the channel allocation problem for throughput maximization in cognitive radio networks with hardware-constrained secondary users. Specifically, we assume…
