Abstract:
Embodiments of the invention provide a method of de-rate matching without NULL bits skipping. Date is received without NULLs and inputted into a LLR combining block. The history data without NULLs is buffered. Log-likelihood ratio (LLR) combining is called before de-rate matching. The output of LLR combining is de-interleaved. The reading pointer is offset to forge NULLs. Finally, de-interleaving output without NULLs is sent to a turbo decoder.
