Abstract
Standard spread-spectrum techniques encounter a severe performance loss under channels with large Doppler spread. It is shown that the novel spread-spectrum technique, called multi-carrier (MC) CDMA, is dual to direct-sequence CDMA. This enables to derive that MC-CDMA is a signalling technique which allows optimum detection under severe Doppler spread. The receiver for this is a RAKE receiver in the frequency domain
