Log-likelihood ratio (LLR) conversion schemes in orthogonal code hopping multiplexing |
Abstract | ||
|---|---|---|
Log-likelihood ratio (LLR) conversion schemes are proposed to reduce the effect of perforations that occur in orthog- onal code hopping multiplexing (OCHM), which was previously proposed to accommodate more downlink channels than the number of orthogonal codewords. The proposed LLR conversion schemes greatly reduce the required signal-to-noise ratio (SNR) in channel decoding even when the perforation probability is high. The performance of the proposed schemes is evaluated by simulation in terms of the required for a 1% block error rate. Index Terms—Demapping, log-likelihood ratio (LLR), orthog- onal code hopping multiplexing (OCHM), perforation. |
