FREQUENCY DIVISION MULTIPLE ACCESS (FDMA) DEDICATED TRANSMISSION SYSTEM, TRANSMITTER AND RECEIVER USED IN SUCH A TRANSMISSION SYSTEM

摘要

The demodulation of data modulated on a set of carriers with equidistant frequencies by a plurality of transmitters (T1 ... Tn) is executed in the present transmission system (TS) by a discrete multitone receiver (DMT-R). The transmitters (T1 ... Tn) in the transmission system (TS) modulate their data on subsets of carriers which form part of the set of carriers with equidistant frequencies. These transmitters (T1 ... Tn) are possibly additionally equipped with a cyclic prefix adder (CPA), synchronization between them is guaranteed if a predefined condition is fulfilled.
