            Abstract : 
The idea of modeling an unknown channel using a broadcast channel was first introduced by Cover1 in 1972. This paper builds on his line of thought to consider priority encoding of communication over unknown channels without feedback, using fixed-length codes and from a single-shot, individual channel perspective. A ratio-regret metric is used to understand how well we can perform with respect to the actual channel realization.
