Method for transmitting and/or receiving large volumes of digital data

摘要

In a method for transmitting and/or receiving large volumes of digital data which are modulated and transmitted in parallel on a plurality of sub-carriers which are orthogonal in relation to one another, using an inverse Fourier transformation at the transmitting end and a synchronisation signal to restore the signal, which is regularly distorted on the transmission path, in the receiver, the synchronisation signal can be transmitted without reducing the useful bandwidth by additively superimposing on the signals modulated on the sub-carriers a cyclically recurring signal sequence as a synchronisation signal, said synchronisation signal having an autocorrelation function with pulse-like behaviour.
