Simulation of telecommunication signal smoothing methods
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.
