Anti-hangup binary quantized DPLL technique for timing recovery in QAM symbol-rate sampled receivers.

Anti-hangup binary quantized DPLL technique for timing recovery in QAM symbol-rate sampled receivers.

This paper presents the statistical performance analysis of a decision directed timing recovery scheme based on a digital phase-locked loop (DPLL) that uses binary quantization and employs an adaptive sequential loop filter (LF) devised in order to prevent the adversary hang-up phenomenon. The propo...
