Abstract
A method includes receiving a signal, which carries data that is encoded with an Error Correction Code (ECC), and correcting the received signal with an adaptive receiver loop. Soft input metrics for the data are computed over the corrected signal. The ECC is decoded using a decoder, which estimates soft output metrics based on the soft input metrics, by operating the decoder in an alternating pattern of external iterations that update one or more of the soft input metrics based on one or more of the soft output metrics, and internal iterations that update the soft output metrics but not the soft input metrics. The adaptive receiver loop is adjusted in a schedule that is defined relative to the pattern of the external and the internal iterations of the decoder.
