Abstract
A transmitter module for a broadband data transmission system for radio communications, comprising at least one polyphase FFT filter bank is described. The at least one polyphase FFT filter bank is established as a synthesis polyphase FFT filter bank, wherein the at least one polyphase FFT filter bank comprises several filter units, wherein the transmitter module is configured to generate a transmission signal by an orthogonal frequency division multiplexing technique, for example by a shaped orthogonal frequency division multiplexing. Moreover, a receiver module for a broadband data transmission system and a data transmission system are described.
