摘要：A coding scheme for coding information having a nonuniform probabilitydistribution function. According to exemplary embodiments, a code word is assigned tothe information corresponding to the peak level of the probability density function, andis referred to as the kernel. New code words having a Hamming distance of 1 to thekernel are then assigned to information adjacent to the peak level of the probabilitydensity function. The new code words are arranged around the kernel in as compact amanner as possible. If there are forbidden code words, the kernel is selectedappropriately and the forbidden words are omitted from the resulting code table.
