Blind channel estimation for space-time coding systems with Baum-Welch algorithm
(IEEE, 2002)
In recent years, space-time coding is proposed to provide significant capacity gains over the traditional communication systems in fading wireless channels. In this paper, we consider the problem of blind estimation of the ...
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 ...
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 ...
