Abstract :
A novel product concatenated scheme for OvCDM is proposed, characterized in that one or more OvCDM codes are as component codes in product concatenated OvCDM. The product concatenated OvCDM system is to make up a product concatenated code with higher spectrum efficiency. The product concatenated OvCDM uses iteratively decoding algorithm based on LOG-MAP algorithm. Comparing with un-concatenated OvCDM, the performance of product concatenated OvCDM is closer to the Shannon limit.
