High-performance low-memory interleaver banks for turbo-codes

Stewart Crozier, Paul Guinand

Abstract: A new method of designing high-performance, low-memory, interleaver banks for turbo-codes is presented. The new interleavers are called dithered relative prime (DRP) interleavers. Only a small number of parameters are required to both store and implement each interleaver in the bank. The error rate performance is similar to that achieved by other good interleaver designs that typically require the storage of all K indexes for each interleaver of length K.
