Abstract:  We investigate the general two-user Broadcast Channel (BC) where an encoder transmits common and private messages to two receivers while being oblivious to the possible channel realizations controlling the communication. We first study the role of Interference Decoding (ID) and then, we investigate a novel encoding technique, namely Multiple Description (MD) coding, where the source transmits common and private descriptions intended to each of the different instances of the channels realizations. Both strategies prove to be very useful in presence of channel uncertainty at the encoder. The benefits of combining these two strategies are emphasized, taking full advantage of the joint optimization of the encoding (MD coding) and the decoding (ID) techniques.
