“…This method allows us to spend the least amount of hardware resources as it does not require additional calculations. To eliminate the amplitude distortion of the signal, a classical algorithm is used for all channel characteristics [6]. The most resourceintensive stage of this algorithm is the calculation of the inverse matrix.…”

The problems of wireless communication systems are investigated. A model and hardware implementation of a system for estimating and correcting amplitude distortions of a radio signal using an algorithm based on Singular Value Decomposition (SVD) has been developed. The analysis of the efficiency of the system when processing the LTE signal is performed. The model was obtained in the Matlab system with modeling the propagation environment, as well as time and frequency tuning blocks using the LTE Toolbox library. FPGA resources with hardware implementation are estimated. Testing the signal-to-noise ratio of the two-antenna equalizer revealed its advantage over the single-antenna configuration by 2.8 dB.
