Optimal primary-secondary user pairing and power allocation in cognitive cooperative multiple access channels
We develop jointly optimal power control and primary-secondary user partnering strategies for a cognitive cooperative multiple access channel with K primary and K secondary users. For each primary user, a cooperating ...
Cognitive Cooperative MAC With One Primary and Two Secondary Users: Achievable Rates and Optimal Power Control
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2014-11)
We consider a three-user fading cognitive cooperative multiple access channel (MAC) with one primary and two secondary transmitters. We propose two encoding/decoding strategies with varying levels of cooperation, based on ...
