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. ...
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 ...
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 ...
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 ...
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 ...
Co-registration of surfaces by 3D least squares matching
(Amer Soc Photogrammetry, 2010-03)
A method for the automatic co-registration of 3D surfaces is presented. Die method utilizes the mathematical model of Least Squares 2D image matching and extends it for solving the 3D surface matching problem The transformation ...
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 ...
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 ...
Maximum likelihood blind channel estimation for space-time coding systems
(Hindawi Publishing Corporation, 2002-05)
Sophisticated signal processing techniques have to be developed for capacity enhancement of future wireless communication systems, In recent years, space-time coding is proposed to provide significant capacity gains over ...
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 ...
