Abstract: This work investigates the “2 by 1” two-user Compound Broadcast Channel. We investigate an evolved encoding scheme, based on the use of Multiple Description (MD) coding, where the source transmits both common and private descriptions to the many channel instances of the same user. We derive the resulting MD inner bound and evaluate it for the compound MISO BC resorting to a Dirty Paper Code (DPC). The suggested MD-DPC “strictly” outperforms Common Description (CD)-DPC and hence, palliates better the effect of channel uncertainty.
