| Abstract: | SML (suboptimal) maximum likelihood) synchronizer which is used to extract the timing waveform in high speed PCM data transmission is studied in this paper. Computer simulation 'analysis and calculation show that SML synchronizer has very good performance; moreover, it is rather immune against channel phase distortion. Experiments have proved the structural simplicity of SML synchronizer and therefore the feasibility of the high speed timing extraction. |
