Abstract

For pt.I see ibid., p.991, 1996. Presently investigated multicarrier code division multiple access (MC-CDMA) concepts explicitly avoid the occurrence of intersymbol interference (ISI), which facilitates the use of simple receivers. Unfortunately, the application of such MC-CDMA concepts cannot be recommended in outdoor environments. In pt. I, an MC-CDMA concept, which overcomes this disadvantage, has been introduced and described mathematically for the first time. The presented MC-CDMA concept explicitly allows ISI. In order to mitigate the effects of multiple access interference (MAI) and ISI, the deployment of joint detection (JD) techniques is proposed. Four JD techniques which are suitable for the application in the presented MC-CDMA concept are introduced. Finally, the performance, which can be achieved by applying the proposed JD techniques in the presented MC-CDMA concept, is analyzed in the case of the uplink
