Query: Exact Random Coding Exponents and Universal Decoders for the Asymmetric
  Broadcast Channel   This work contains two main contributions concerning the asymmetric broadcast
channel. The first is an analysis of the exact random coding error exponents
for both users, and the second is the derivation of universal decoders for both
users. These universal decoders are certain variants of the maximum mutual
information (MMI) universal decoder, which achieve the corresponding random
coding exponents of optimal decoding. In addition, we introduce some lower
bounds, which involve optimization over very few parameters, unlike the
original, exact exponents, which involve minimizations over auxiliary
probability distributions. Numerical results for the binary symmetric broadcast
channel show improvements over previously derived error exponents for the same
model.
