Аннотация

The filtered orthogonal frequency division multiplexing method used for the transmission of the signals with spectra in adjacent frequency subbands has been analyzed. Three types of errors appearing when applying the method for quadrature amplitude modulation symbols transmission have been described. For the error reduction the modified algorithm based on cyclic convolution properties has been developed. In the numerical experiment, the classical and modified algorithms have been applied in combination with modulation schemes of large order.
