A method and apparatus for selecting interleaver sizes for turbo codes is provided herein. During operation information block of size K is received. An interleaver size K' is determined that is related to K'', where K'' from a set of sizes; wherein the set of sizes comprise K'' = Ep x f, pmin <= p <= pmax; fmin <= f <= f max, wherein a is an integer and f is a continuous integer between fmin andfmax, p takes integer values between pmin and pmax, a>1, pmax> pmin, pmin>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.
