Abstract: Multi address interference's effect on parallel acquistion performance of DS-Multi-carrier CDMA system under typical indoor radio channel is discussed.Moreover,a comparison of acquistition performance impairment produced by the MAI of DS-MC-CDMA and DS-single-carrier CDMA is also made.Results are given in terms of average acquistion time obtained by means of simulations and analytical computation.

Key words: code division multiple access, multicarrier CDMA, multiple access interference, acquisition
