Abstract :
A novel bit-interleaved serial concatenated scheme for OvCDM is studied, characterized in that one or more OvCDM codes are as component codes in bit-interleaved serial concatenated OvCDM to make up such a bit-interleaved serial concatenated code with higher spectrum efficiency. The bit-interleaved serial concatenated OvCDM uses iterative decoding algorithm based on LOG-MAP Algorithm with soft input soft ouput (SISO). Comparing with un-concatenated OvCDM, the bit-interleaved serial concatenated OvCDM is easier to achieve higher spectral efficiency and the decoding complexity is reduced significantly.
