On multi-carrier code division multiple access (MC-CDMA) modem design

Gerhard Paul Fettweis, A.S. Bahai, Kazem Anvari

Open publisher page 81 citations

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.>
