Blind interference cancellation for multicarrier DS-CDMA

In the mobile communication systems, many problems are raised due to the increase of the number of users. More efficient communication techniques must reflect the demand of users. An efficient method to solve fading and interference is multicarrier direct sequence code division multiple access systems. Thus, in this paper, we adopted multicarrier direct sequence code division multiple access which is proposed by Milstein. To solve multiple access interference efficiently, we must be able to use interference cancellation techniques. In this paper, we proposed blind interference cancellation that does not need training sequence. The MCBMOE interference receiver is proposed to solve interference problem due to multiuser access at MC DS-CDMA systems. The simulations show that proposed method has a good performance more than the conventional methods.
