Abstract

A device for transmitting an information signal having several transmit signals has a modulator for generating a first and a second transmit signal. The first transmit signal is transmittable via a first spatial emitter, and the second transmit signal is transmittable via a second spatial emitter. The modulator has an OFDM control stage to load a first group of OFDM carriers with first information to generate the first transmit signal, and to load a second group of OFDM carriers with second information to generate the second transmit signal. The first group of OFDM carriers differs from the second group of OFDM carriers, and the first information differs from the second information. The present invention further provides a corresponding method and a computer program for transmitting an information signal.
