Abstract

An MC/JD-CDMA (multicarrier joint detection code division multiple access) mobile radio system concept based on UTRA-TDD (UMTS terrestrial radio access-time division duplex) is investigated. The focus of the paper is the system performance in non-contiguous frequency bands since this is favourable with respect to the co-existence with narrowband second generation mobile systems. In particular, two channel estimation approaches for MC/JD-CDMA are considered, a test symbol based approach which is comparable with the one used in GSM as well as a chip based approach similar to the estimation technique which is proposed for UTRA-TDD. The simulation results presented for the UMTS/IMT-2000 wideband channel models indicate that the performance of MC/JD-CDMA does not suffer due to the operation in a non-contiguous frequency band
