Description	At present in radiocommunication is typical trend to convert from analog systems, which cannot reach essential quality improvement, to digital ones. One of those is DRM system, which is considered as replacement of classical amplitude modulation transmission in longwave, middlewave and shortwave bands. The base of OFDM modulation in DRM is fast Fourier transformation (FFT) computing. This paper deals with analysis of dependence of available results accuracy on used number of bits, FFT dimension and algorithms used in FFT computation.
