Effects of symbol transition density on the performance of the data transition tracking loop at low signal-to-noise ratios
S. Million, S.M. Hinedi · 2002
Effects of the data transition variation on the performance of the digital data transition tracking loop (DTTL) symbol synchronizer are addressed for symbol SNRs and window sizes of interest. The data transition variation will affect the DTTL performance by introducing an additional timing jitter which results in additional receiver loss. Numerical and simulation results for both tracking and acquisition are presented.
