Achievable rates for two user cooperative OFDMA
(IEEE, 2010)
We propose two encoding strategies for a two user cooperative Orthogonal Frequency Division Multiple Access (OFDMA) system, based on block Markov superposition encoding. We obtain the expressions for the resulting achievable ...
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 ...
Enabling cooperation, resource allocation and receiver selection across cells: complementary fractional frequency reuse
(IEEE, 2013)
For a multi-cell multiple access channel, we develop a comprehensive cooperative communication framework: we propose a novel complementary fractional frequency reuse (FFR) strategy tailored specifically for pairwise user ...
Energy harvesting cooperative multiple access channel with data arrivals
(IEEE, 2016)
We consider an energy harvesting two user cooperative Gaussian multiple access channel (MAC), where both of the users harvest energy from nature. The data packets arrive intermittently over time. The users overhear each ...
Optimal and near-optimal partner selection algorithms in cooperative OFDMA
(IEEE, 2012)
We obtain the jointly optimal power allocation and partner selection policies, that maximize the sum rate of a cooperative OFDMA system with mutually cooperating pairs of users. We show that the power allocation and partner ...
Energy harvesting cooperative multiple access channel with decoding costs
(IEEE, 2016)
We consider an energy harvesting cooperative multiple access channel (AC) with decoding costs. In this setting, users cooperate at the physical layer (data cooperation) in order to increase the achievable rates. Data ...
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 ...
Cooperative multiple access under energy harvesting constraints
(Institute of Electrical and Electronics Engineers Inc, 2015)
We consider a cooperative multiple access channel (MAC) with two energy harvesting transmitters. The transmitters perform delay constrained transmission, i.e., every information block is encoded, transmitted and decoded ...
Energy and data cooperation in energy harvesting multiple access channel
(IEEE, 2016)
We consider the energy harvesting two user Gaussian multiple access channel (MAC), where both users harvest energy from nature. The users cooperate at the physical layer (data cooperation) by establishing common messages ...
