Abstract
The invention relates to a transmitting and receiving method and a radio system. In a transmitter the signals to be transmitted are spread coded in means and modulated by subcarriers in means. In a receiver (R) the signals are demodulated in means and submitted to multiuser detection in means by using the subcarriers to limit the number of detectable signals in the means. The receiver uses multiuser detection for reducing multiple access interference and correcting frequency-selective fading.
