Abstract
A serial concatenated scheme for Overlapped Code Division Multiplexing (OvCDM) system is proposed, characterized in that one or more OvCDM codes are as component codes in serial concatenated OvCDM to make up such a concatenated code with higher spectrum efficiency. The serial concatenated OvCDM uses iterative decoding algorithm based on LOG-MAP Algorithm with soft input soft ouput (SISO). As the simulation results show, the performance of serial concatenated OvCDM is closer to the Shannon limit than that of un-concatenated OvCDM.
