    • Noncoherent space-time coding: an algebraic perspective 

      El Gamal, H.; Aktas, D.; Damen, M. O. (IEEE, 2005-06)
      The design of space-time signals for noncoherent block-fading channels where the channel state information is not known a priori at the transmitter and the receiver is considered. In particular, a new algebraic formulation ...
    • Nondata-aided channel estimation for OFDM systems with space-frequency transmit diversity 

      Cırpan, H. A.; Panayırcı, E.; Doğan, H. (Institute of Electrical and Electronics Engineers, 2006)
      This paper proposes a computationally efficient nondata-aided maximum a posteriori (MAP) channel-estimation algorithm focusing on the space-frequency (SF) transmit diversity orthogonal frequency division multiplexing (OFDM) ...
