The article discusses the use of methods for smoothing telecommunication signals distorted by noise during transmission over radio communication channels. Signal smoothing is simulated for different values of the signal-to-noise ratio and the width of the smoothing window. The optimal width of the smoothing window and the maximum pressure coefficient were determined as a function of the input noise level. Comparison of the results showed that the most effective smoothing methods are based on weighting signal samples using a Gaussian function and a moving averaging. Moreover, the moving averaging method is easier to implement and use.
