摘要
There are considered the interference-immunity improvement techniques of the OFDM (Orthogonal Frequency Division Multiplexing) - modulation because of hexagonal grids application on a plane as well as the method of cyclic prefix removal in using the Gabor wavelet-functions. The suggested method with application of the Gabor wavelets allows one to exclude the OFDM-system cyclic prefix. That leads to efficiency increase of using a frequency band to 25%.
