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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
