Cooperative strategies and achievable rates for two user OFDMA channels
(IEEE-INST Electrical Electronics Engineers Inc, 2011-12)
We propose three encoding strategies for a two user cooperative Orthogonal Frequency Division Multiple Access (OFDMA) system, based on block Markov superposition encoding (BMSE). We obtain the expressions for the resulting ...
Optimal primary-secondary user pairing and power allocation in cognitive cooperative multiple access channels
(IEEE, 2014)
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 ...
Optimum power control for transmitter cooperation in OFDMA based wireless networks
(IEEE, 2011)
For a cooperative orthogonal frequency division multiple access (OFDMA) system with two transmitters (TXs), and full channel state information (CSI), we obtain the optimal power allocation (PA) policies which maximize the ...
A new block Markov coding strategy for pairwise and collective cooperation in the three user MAC
(IEEE, 2013)
For a three user cooperative multiple access channel (MAC), we propose a new block Markov superposition encoding strategy, which enables all three users to cooperate collectively as well as in pairs. We obtain the resulting ...
Delay tolerant cooperation in the energy harvesting multiple access channel
(IEEE, 2016)
We consider the optimum transmit scheduling problem for a two user energy harvesting cooperative multiple access channel. We assume a slotted model where energy harvests in each slot are known a priori. We propose a delay ...
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 ...
