FIELD: information technology. ^ SUBSTANCE: invention relates to communication technology and can be used for a multi-band multiple station access system with orthogonal frequency division multiplexing (OFDMA). The bandwidth is installed for signal transmission by radio resources, and the bandwidth is made up of an edge band and a central band. The narrow-band radio-resources are assigned a part of a transmission band which is at least partially located within the limits of the edge band. ^ EFFECT: increased efficiency of bandwidth utilisation due to processing by the window method without a significant impact on the basic physical design of receiver filters. ^ 7 cl, 9 dwg |
