Research of Opportunities for Reducing Transmission Errors in Orthogonal Frequency-Division Multiplexing Signals

摘要

The paper discusses the features of the transfer of orthogonal frequency-division multiplexing signals. The main advantages of using the signals if we compare it to a single-carrier scheme are their ability to withstand the difficult conditions in the channel. The block wiring diagram for receiving modems with a module of multiple averaging is shown. The comparison of using Single Input Single Output, Single Input Multiple Output (coherent averaging) and Single Input Multiple Output (the proposed method) is carried out. The graphical dependence are constructed and it is shown that the proposed approach, the number of errors can be reduced by several times.
