Abstract:
1. A data receiver comprising: an analog-to-digital converter configured to convert an analog signal into a digital signal based at least in part on a first sampling phase; a non-Viterbi decoder configured to decode the digital signal into a first set of decoded bits using a non-Viterbi tree search algorithm and outputting the first set of decoded bits on a feedback signal path; wherein the feedback signal path is connected between the non-Viterbi decoder and a timing recover module; a Viterbi decoder configured to decode the digital signal from the analog-to-digital converter into a second set of decoded bits with a Viterbi detection algorithm; wherein a decoded output from the data receiver is the second set of decoded bits from the Viterbi decoder; wherein the timing recovery module is configured to: wherein the non-Viterbi decoder is configured to perform the non-Viterbi tree search algorithm comprising:
