Narrow-Band Interference Rejection in a Multi-Carrier CDMA System Using Transform Domain Adaptive Filter
Jun Zhang, Wei Zhu · Systems engineering and electronics · 2001
The Multi-Carrier CDMA (MC-CDMA) system combines the advantages of orthogonal frequency division multiplexing (OFDM) system with that of CDMA system. It has been paid much attention to since it was put out in 1993. In this paper, the transform domain adaptive filter is used in the MC-CDMA system to reject narrow-band interference on the AWGN channels. The performance of the MC-CDMA system using the threshold exciser is compared with that of the system using the transform domain adaptive filter. From the simulation results, the performance of the MC-CDMA system using the transform domain adaptive filter is much better than that of the system using the threshold exciser.
