Abstract  Abstract

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?=a pxf pmin?p?pmax; fmin?f?fmax wherein a is an integer and f is a continuous integer between fmin and fmax 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.
