Joint setting of demodulating carrier phase, sampling time and equalizer gain parameters in synchronous data transmission systems

摘要: Apparatus and method for the joint setting in synchronous digital data transmission systems of parameters demodulating carrier phase, sampling time transversal equalizer tap gains based on a common mean-square error minimization criterion. Responsive to test pulses traversing distorting medium locally generated an ideal filter simultaneous correlations are made with each output difference between actual responses control gap gains, derivative response received signal time, quadrature transform phase. Optimum these critical is thereby guaranteed.
