Abstract. The method of transmission of the discrete messages on the basis of the intellectual
modem with multifrequency modulation in-process is offered. Modem optimization
is carried out on the basis of synthesis of optimum finite signals in the individual
channels not calling the intersymbol distortions and ensuring maximum value of
a signal/noise ratio on entries of matched filters of the demodulator. The estimation
of parameters of the modem for the purpose of smoothing of performances of the
is frequency-limited communication channel is carried out on the basis of a method
of an optimum recurrent filtering. The analysis
of effectiveness and a noise stability of the modem is given theoretical.
Keywords: system a data transmission, the intellectual modem, a
multifrequency method of modulation, optimum finite signals, effectiveness, a
noise stability.
