In [26] the authors study the threshold probability of a code C with a given distance d, i.e. the crossover probability (C) of a binary symmetric channel such that the error probability of maximum likelihood decoding of C in this channel equals 1=2: They give a lower bound on (C) via an upper bound on ....

....1 to error exponents for the best possible spherical codes : we shall see that even in this case, the very general exponential upper bound of Theorem 1 misses the right exponent by only a small constant. 2 Overview of the proof of Theorem 1 The proof of Theorem 1 follows ideas developed in [10, 11] where a result of a similar nature is proved for the binary symmetric channel. The basic idea is to 4 derive an inequality of the form d d P e ( f(P e ( through a geometric interpretation of P e ( and d d P e ( and then integrate this inequality to obtain Theorem 1. The ....
