Abstract :
Let 
be a code of 
vectors whose components consist of 
ones and 
zeros. The vectors are transmitted with equal probability over the asymmetric channel whose error probabilities for transmitted zeros and ones equal respectively 
and 
(such channels arise in optical communication). The problem of determining for fixed values of the parameters 
those codes which achieve minimum error probability is studied. The problem is solved for 
. Partial results are obtained for all .
