SUMMARY OF MASTER DISSERTATION 
The master's thesis shows the relevance of increasing the data transfer rate 
for OFDM wireless systems.
The expediency of applying a scientific and 
methodological mathematical model of system analysis for the development of a 
high-speed OFDM system is confirmed. 
Development of a mathematical model of the system using OFDM 
technology that implements multiplication with orthogonal frequency division 
based on the formulation of the problem of system analysis, DVP and modules 
based on the use of arithmetic methods and algorithms. 
The results obtained show that the use of the developed mathematical model 
of the Dobeshi-4 fiberboard made it possible to reduce the time spent by 1.32 times 
on performing the main operation when processing 16-bit data in the final Galois 
field.
