Thresholds optimization for one-bit feedback multi-user scheduling
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
We propose a new one-bit feedback scheme with scheduling decision based on the maximum expected weighted rate. We show the concavity of the 2-user case and provide the optimal solution which achieves the maximum weighted ...
Centralized and Distributed Cognitive Relay-Selection Schemes for SWIPT Cognitive Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
We investigate the model of a single primary-transceiver pair with multiple secondary-transceiver pairs. The secondary pairs can act as relays for the primary transmitter enabling access to its channel resources. Each ...
Energy-efficient cooperative cognitive relaying schemes for cognitive radio networks
(
Elsevier B.V.
, 2018 , Article)
We investigate a cognitive radio network in which a primary user (PU) may cooperate with a cognitive radio user (i.e., a secondary user (SU)) for transmissions of its data packets. The PU is assumed to be a buffered node ...
