Fig. 6. A 7× 7 binary pattern x is transmitted through the channel with the set of 2-D isolated-bits patterns as the set of harmful patterns. The bits x2,6, x3,5, x3,6, x3,7, x4,6, x6,7, x7,6 and x7,7 belong to the 2-D isolated-bits patterns. Passing through the channel, the probability of error for these bits is αb, and for the rest of them is αg .
