Query: Polar Coding for the Large Hadron Collider: Challenges in Code
  Concatenation   In this work, we present a concatenated repetition-polar coding scheme that
is aimed at applications requiring highly unbalanced unequal bit-error
protection, such as the Beam Interlock System of the Large Hadron Collider at
CERN. Even though this concatenation scheme is simple, it reveals significant
challenges that may be encountered when designing a concatenated scheme that
uses a polar code as an inner code, such as error correlation and unusual
decision log-likelihood ratio distributions. We explain and analyze these
challenges and we propose two ways to overcome them.
