description: This work is devoted to studying the influence of the limited dynamic range of a power amplifier on the noise immunity of receiving SEFDM signals in a system using MIMO.
In the course of the work, a simulation model of the algorithm was developed in the Matlab modeling environment, which includes the formation and reception of a signal in the SISO and MIMO system, calculation of the probability of error. The influence of the SSPA power amplifier on the noise immunity is analyzed. A study of the influence of the limited dynamic range of a power amplifier on the noise immunity of receiving SEFDM and OFDM signals in a system using MIMO using a model of a power amplifier SSPA with a parameter responsible for the smooth transition of the characteristic from a linear section to a saturation section of two showed that the amount of distortion introduced by the power amplifier depends on the offset of the operating point of the amplifier, as well as on such signal parameters as the number of subcarriers, the type of module used in the system ratios, compaction coefficient and the presence in the system of technology with multiple inputs and multiple outputs.
