This paper shows that the Maddah-Ali-Tse (MAT) scheme, which achieves the symmetric capacity of two example broadcast channels with strictly causal state information at the transmitter, is a simple special case of the Shayevitz-Wigger (SW) scheme for the broadcast channel with generalized feedback, which involves block Markov coding, Gray-Wyner compression, superposition coding, and Marton coding. Focusing on the class of symmetric broadcast channels with state, we derive an expression for the… CONTINUE READING
