Achieving the capacity region boundary of fading CDMA channels via generalized iterative waterfilling
(IEEE, 2006-11)We characterize the optimum power control policies that achieve arbitrary rate tuples on the boundary of the, capacity region of a power controlled, code division multiple access (CDMA) system in a fading channel with ... -
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 ... -
Design and performance analysis of a novel trellis coded space-time-frequency OFDM transmission scheme
(Wiley-Blackwell, 2008-01)In this paper a new transmit diversity technique is proposed for wireless communications over frequency selective fading channels. The proposed technique utilises orthogonal frequency division multiplexing (OFDM) to transform ... -
Iterative channel estimation approach for space-time/frequency coded OFDM systems with transmitter diversity
(Assoc Elettrotecnica Ed Elettronica Italiana, 2004-06)Focusing on transmit diversity orthogonal frequency division multiplexing (OFDM) transmission through frequency selective channels, this paper pursues novel iterative channel estimation approaches for both space-frequency ... -
Linear expansions for frequency selective channels in OFDM
(Elsevier GMBH, 2006)Modeling the frequency selective fading channels as random processes, we employ a linear expansion based on the Karhumen-Loeve (KL) series representation involving a complete set of orthogonal deterministic vectors with a ... -
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 ... -
Power control for two user cooperative OFDMA channels
(IEEE-INST Electrical Electronics Engineers Inc, 2013-01)For a two user cooperative orthogonal frequency division multiple access (OFDMA) system with full channel state information (CSI), we obtain the optimal power allocation (PA) policies which maximize the rate region achievable ...
