The use of methods of intellectual decision support in modern infocommunication systems OFDM allows to ensure high reliability of data transmission due to their adaptation to various destructive influences. To make an optimal decision that allows to effectively counteract such impacts, it is necessary to conduct a multi-scale analysis of the parameters of the communication channel using a discrete wavelet transform. The purpose of research is to improve the accuracy and reliability of the implementation of discrete wavelet transform in infotelecommunication systems OFDM. To achieve this aim it is proposed to use nonpositional modular codes, in particular code of residue number system. The paper presents the implementation of discrete wavelet transform based on Haar discrete wavelet transform by code of residue number system (RNS). It is shown that the use of the modular RNS code does not only improve the accuracy in the OFDM-DWT, but helps to detect and correct errors that occur in the process of transformation. Thus, the application of new modular technologies in infotelecommunication systems OFDM allows not only to increase the computational accuracy, but also to ensure the correct result due to parallelization at the level of operation and processing of low-bit data OFDM.
