Blind interference cancellation for multicarrier DS-CDMA
Dae-Ho Woo, Youn-Shik Byun · 2004
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. The multicarrier direct sequence code division multiple access systems is an efficient method in solving both fading and interference. Thus, in this paper, we adopted the multicarrier direct sequence code division multiple access proposed by Milstein. To solve the 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 the training sequence. The MCBMOE interference receiver is proposed to solve interference problem due to the multiuser access at MC DS-CDMA systems. The simulations show that proposed method has a good performance than the conventional methods.
