PROBLEM TO BE SOLVED: To provide a method and apparatus for selecting interleaver sizes for turbo codes. SOLUTION: During operation, an information block of size K is received. An interleaver size K' is determined that is related to K", where K" is from a set of sizes; wherein the set of sizes comprise K"=a<SP>P</SP>×f, p<SB>min</SB>≤p≤p<SB>max</SB>; f<SB>min</SB>≤f≤f<SB>max</SB>, wherein (a) is an integer and (f) is a continuous integer between f<SB>min</SB>and f<SB>max</SB>, and (p) takes integer values between p<SB>min</SB>and p<SB>max</SB>, a>1, p<SB>max</SB>>p<SB>min</SB>, p<SB>min</SB>>1. The information block of size K is padded into an input block of size K using filler bits, if needed. Encoding is performed using the original input block and the interleaved input block to obtain a codeword block using a turbo encoder. The codeword block is transmitted through the channel.
