Achievable rates for the three user cooperative multiple access channel
(IEEE, 2008)
For a three user Gaussian multiple access channel (MAC), we propose a new superposition block Markov encoding based cooperation scheme. Our scheme allows the three users to simultaneously cooperate both in pairs, and ...
Window and backwards decoding achieve the same sum rate for the fading cooperative Gaussian multiple access channel
(IEEE, 2006)
For a two user fading Gaussian multiple access channel with user cooperation, we show that window decoding achieves the same sum rate as backwards decoding, when the encoding is done using block Markov superposition coding. ...
Channel adaptive encoding and decoding strategies and rate regions for the three user cooperative multiple access channel
(IEEE, 2008)
For a cooperative Gaussian multiple access channel (MAC), we propose a new channel adaptive three user cooperation strategy, based on a non-trivial extension of block Markov super-position encoding. We obtain the expressions ...
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 ...
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 ...
Improving age of information in random access channels
(Institute of Electrical and Electronics Engineers Inc., 2020-07)
We study Age of Information (AoI) in a random access channel where a number of devices try to send status updates over a common medium. Assuming a time-slotted scenario where multiple transmissions result in collision, we ...
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 ...
When to pull data for minimum age penalty
(IEEE, 2021-10-18)
A communication receiver that wants to pull data from a remote sensor by exploiting wireless energy transfer is considered. The receiver has a long-term average energy budget for this operation, and its goal is to keep the ...
