Query: Iterative network-channel decoding with cooperative space-time
  transmission   One of the most efficient methods of exploiting space diversity for portable
wireless devices is cooperative communication utilizing space-time block codes.
In cooperative communication, users besides communicating their own
information, also relay the information of other users. In this paper we
investigate a scheme where cooperation is achieved using two methods, namely,
distributed space-time coding and network coding. Two cooperating users utilize
Alamouti space time code for inter-user cooperation and in addition utilize a
third relay which performs network coding. The third relay does not have any of
its information to be sent. In this paper we propose a scheme utilizing
convolutional code based network coding, instead of conventional XOR based
network code and utilize iterative joint network-channel decoder for efficient
decoding. Extrinsic information transfer (EXIT) chart analysis is performed to
investigate the convergence property of the proposed decoder.
