Channel estimation for space-time block coded OFDM systems in the presence of multipath fading
(IEEE, 2002)In this paper, a computationally efficient, non-data-aided maximum a posterlori(MAP) channel estimation algorithm is proposed for orthogonal frequency division multiplexing (OFDM) systems with transmitter diversity using ... -
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 ... -
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 ... -
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 ...
