Performance of network coded cooperation over the Gaussian channel in which multiple communication nodes send each one's message to a common destination is analyzed. The nodes first broadcast the message, and subsequently relay the XOR of subset of decoded messages to the destination. The received vector at the destination can be equivalently regarded as the output of a point-to-point channel, except that the underlying codes are drawn probabilistically and symbol errors may occur before transmission of a codeword. We analyze the error performance of this system from coding theoretic viewpoint.
