摘要
Basedonthetheoryofmulticarrier(MC)techniqueandtheRakereceiver,amulticarrierDSCDMARakesystemisproposed,whereadatasequencemultipliedbyaspreadingsequencemodulatesmultiplecarriers.ThereceiverprovidesaRakeforeachsubcarrier,andtheoutputsoftheRakesarecombinedbyamaximal-ratiocombiner.Theaverageprobabilityoferrorofthesystemisderivedfromanuncorrelatedsubcarrierandfrequency-selectivefadingchannelmodel.ThesystemperformancesareevaluatedoverRayleighfadingchannelwithanexponentialmultipathintensityprofile(MIP)andwitharectangularMIP,respectively,whenmultipathinterferenceispresent.ItisfoundthatthiskindofmodelhaslargersuperiorityinanexponentialMIPthaninarectangularMIP.
