denotes the range of F. Given the equiprobability condition for Ci, the probability of every symbol in x0 x1 . . . xn 1 2 X being included in F is  n  n j F j M Qc : jR q1 ; q2 ; . . . ; qc j i 1 qi Therefore the number of codewords in C is approximated by  n Y  n c M M jCi j Qc : jCj jXj Qc i 1 qi i 1 qi i 1 Q.E.D. Table 13.4, shown later, indicates that this approximation is highly accurate for the class of codes indicated. 3. Decoding Procedure A maximum likelihood decoding, in general, gives a low probability of erroneous decoding. A received word U 0 u00 u01 . . . u0n 1 can be decoded by a brute force search through the u set C of codewords to nd a codeword ^0 ^1 . . . ^n 1 2 C that maximizes the probability u u

p u0i j^i : u
In the conventional block codes used in communication and memory systems, a brute force search, in general, requires a prohibitively long time because there exists a huge number of codewords. In contrast, the indicated code is designed to generate a codebook for M-ary data, such as postal codes and product numbers, where the number of codewords is relatively small, and also the constraint on decoding delay is not so severe compared to the communication and memory systems. Therefore the maximum likelihood decoding using brute force search is feasible for the codes.
