Power control for fading cooperative multiple access channels
(IEEE, 2007-08)
For a fading Gaussian multiple access channel with user cooperation, we obtain the power allocation policies that maximize the average rates achievable by block Markov superposition coding, subject to average power ...
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 ...
Power control in the cognitive cooperative multiple access channel
(IEEE, 2012)
We extend several encoding and decoding techniques from cooperative communications framework, to a cognitive radio system consisting of a primary user (PU) and a secondary user (SU), sending their messages to a common ...
