Abstract :
To increase the spectrum efficiency in mobile communications and to support variable data rates, multi-code code division multiple access (MC-CDMA) systems have been proposed which allow to support variable source data rates by variation of the set of code sequences assigned to every user. In this paper, different types of sequences sets are discussed and their performance is analyzed for a scenario with different data rates
