Effects of carrier frequency accuracy on quasi-synchronous, multicarrier DS-CDMA communications using optimized sequences.

It is known that the multiple access interference (MAI) of a quasi-synchronous (QS) multicarrier direct signal code division multiple access (DS-CDMA) system can be substantially reduced by using signature sequences having optimized cross correlation at small shifts around the origin. This paper sho...
