Modified PIC in MC-CDMA systems
Zhanyun Duan, T.H. Stitz, Mikko Valkama, Markku Renfors · 2004
In this paper, we propose a modified parallel interference cancellation (PIC) approach for MC-CDMA systems. Compared with conventional PIC, modified PIC can improve BER performance at lower number of subchannels in both downlink and uplink channels and has the same performance as conventional PIC when the number of subchannels is sufficiently large. Modified PIC also has reduced implementation complexity in the uplink scenarios.
