Abstract :
Much effort has been devoted to the design of wireless communication systems for high data rate applications. MC-CDMA (multi-carrier code division multiple access) is able to transmit at high data rate because it converts to slow data rate at serial to parallel converter. We introduce the MC-CDMA system based on non-linear MMSE (minimum mean square error). The purpose of this paper is to design MC-CDMA with non-linear adaptive filter (called n-equalizer), which has the ability to alleviate problems, associated with various noise components. The Monte-Carlo simulation method is used to show the performance of the system suggested here
