Abstract
The output signals from a transmitter in modern digital transmission systems (DTS) are usually square-wave pulses, and the frequency response (FR) is only corrected on the receiving side [1]. We know that for identical frequency responses of the cable and an identical transmitter output power, simultaneous optimization of the FR of the transmitted signal and the receiving corrector (RC) can improve the signal-to-noise ratio (S/N) at the output of the decision unit (DU) of the regenerator (Reg) [2, 3]. However, the literature contains no information on the specific advantages of optimization under different conditions (section length, signal frequency band, or type of cable). This paper describes one possible method of determining the optimum transmitter and receiver characteristics and also presents results of calculations of the improvement in the noise immunity of the output signal of a decision unit obtained by optimization under a variety of specific conditions.
