Abstract
Disclosed is a method for using a different symbol timing for users so as to reduce a multiple access interference component in a multi-carrier code division multiple access (MC-CDMA) system. For this purpose, the presented invention involves dividing the users of the MC-CDMA system into two groups and applying an offset to the symbol timing between the user groups to cause a symbol transition of the opposite user group in the middle of the symbol interval, thereby reducing the multiple access interference component included in a symbol decision variable after a chip combination.
