Researching of noise immunity of communication channels with phase manipulation to the effects of unintentional non-stationary interference
This article considers the model of impact of non-stationary interference on the communication channels with phase manipulation. As indicator that determines the degree of interference factor is used in the lifetime of non-stationary interference factor. It calculates the concentration of its energy at a fixed average power in some limited time domain of the signal. A comparison of the results of the impact of unintentional non-stationary interference in communication channels with phase manipulation and different types of error-correcting coding. It is shown that under certain values of the lifetime of non-stationary interference factor for low signal-to-interference they can have more dangerous effects on communication channels than the continuous noise interference, increasing BER. Error-correcting coding has a significant impact on the reception of signals in the conditions of influence of non-stationary interference. Reed-Solomon codes have a high correcting ability when exposed to non-stationary interference.
