description: The work is devoted to assessing the distortion of SEFDM signals introduced by a power amplifier and studying the noise immunity of receiving OFDM and SEFDM symbols taking into account a power amplifier using a peak factor and Cubic Metric. Metrics are calculated and compared using the graphs of the dependence of the peak factor and Cubic Metric on the standard deviation of signal distortions. An algorithm has been developed for evaluating the noise immunity of receiving signals with OFDM and SEFDM, based on the grouping of metrics and calculating the probability of erroneous reception of bits on each metric interval. Using this algorithm, we plotted the dependence of the probability of erroneous reception of bits on the average values ââof metrics in each interval for different types of modulations and values ââof the offset of the operating point. The graphs are analyzed depending on the variable parameters, and based on these data, a comparison is made of the peak factor and Cubic Metric as a metric for evaluating noise immunity. The main evaluation criterion is the range of variation in the probability of erroneous reception.
