Two groups of algorithms for solving the problem are analysed: those based on the knowledge of channel properties and the knowledge of signal source properties. The results of modeling the algorithms under consideration are given as applied to the problem of controlling data transmission rail channels widely used in railway transport.</p>Channelsignal restorationsignal separationinverse filteradaptive filtermultichannel adaptive filterincorrect problemstabilityregularizationregularization parameterКаналвосстановление сигналовразделение сигналовобратный фильтрадаптивный фильтрмногоканальный адаптивный фильтрнекорректная задачаустойчивостьрегуляризацияпараметр регуляризации
