Abstract
A system and a method are disclosed for determining early termination during an iterative detection and decoding (IDD) procedure. The method may include computing, during the IDD procedure, one or more log-likelihood ratios (LLRs) of one or more cyclic-redundancy checks (CRC), and determining that at least one of the LLRs predict a failure of a CRC check and, in response, terminating the IDD procedure.
Claims21
A method comprising:
- computing, during an iterative detection and decoding (IDD) procedure, one or more log-likelihood ratios (LLRs) of one or more cyclic-redundancy checks (CRC);
- and
- determining that at least one of the LLRs predict a failure of a CRC check and, in response, terminating the IDD procedure.
A receiver comprising:
- a processing circuit comprising a detector and a decoder coupled with the detector, wherein the processing circuit is configured to:
- compute, during an iterative detection and decoding (IDD) procedure, one or more log-likelihood ratios (LLRs) of one or more cyclic-redundancy checks (CRC);
- and
- determine that at least one of the LLRs predict a failure of a CRC check and, in response, terminating the IDD procedure.

A method comprising:
- performing at least two global iterations (GI) of an iterative detection and decoding (IDD) procedure;
- computing, during the IDD procedure, log-likelihood ratios (LLRs) for each code block of a transmit block in response to the transmit block failing a CRC check after a first GI of the IDD procedure;
- and
- determining that a processing budget for a second GI of the IDD is greater than a remaining code block processing budget, in response to determining that at least one of the LLRs predict a failure of a CRC check and, in response terminating the IDD procedure.
