Abstract :
Let { v_{1}, \\cdots , v_{N} } be a code of N vectors whose components consist of m ones and (n - m) zeros. The vectors are transmitted with equal probability over the asymmetric channel whose error probabilities for transmitted zeros and ones equal respectively 0 and p, 0 < p < 1 (such channels arise in optical communication). The problem of determining for fixed values of the parameters N, n, m, p those codes which achieve minimum error probability is studied. The problem is solved for N \\leq 3 . Partial results are obtained for all N .
