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 ...
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 ...
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 ...
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 ...
Maintenance policy analysis of the regenerative air heater system using factored POMDPs
(Elsevier Ltd, 2022-03)
Maintenance optimization of multi-component systems is a difficult problem. Partially Observable Markov Decision Processes (POMDPs) are powerful tools for such problems under uncertainty in stochastic environments. In this ...
