摘要

Method and apparatus for iterative timing recovery for FTN signaling are provided. The iterative timing recovery method and apparatus uses a feedback timing error signal from a forward error correction block with an additional equalizer prior to a maximum a posteriori (MAP) decoder which matches the equalized FTN signal to a truncated inter-symbol interference (ISI) target. A timing error is then generated using a modified M&M timing error detector.
