Presently investigated multicarrier code division multiple access (MC-CDMA) concepts explicitely avoid the occurence 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. I n [l], an MC-CDMA concept, which overcomes this disadvantage, has been introduced and described mathematically for the first time. The presented MC-CDMA concept explicitely allows ISI. In order to mitigate the effects of multiple access interference (MAI) and ISI, the deployment of joint detection (JD) techniques is proposed here. Four JD techniques which are suitable for the application in the presented MC-CDMA concept will be introduced in this paper. Finally, the performance, which can be achieved by applying the proposed JD techniques in the presented MC-CDMA concept, will be analyzed in the case of the uplink.
