OFDM method.
• OFDM is one of the methods of digital signal modulation that allows increasing the data transfer rate due to the reasonable use of communication channels and data transmission method. The main reason for the appearance and application of this signal processing method is the search for ways to combat broadband interference – the main reason for poor communication in conditions of a large number of large-sized obstacles in the form of multi-storey residential buildings and other buildings.
