Asymptotics of the error probability in quasi-static binary symmetric channels. In: 2017 IEEE International Symposium on Information Theory (ISIT);2017 Jun 25-30; Aachen, Germany.

After the leading term, namely the outage probability, the next two terms are found to be proportional to log n n and 1 n respectively. Explicit characterizations of the respective coefficients are given. The resulting expansion gives an approximation to the random-coding union bound, accurate even at small codeword lengths.application/pdfeng© 2017 IEEE. Personal use of this material is permitted.
