Abstract

In this paper, we propose a narrowband interference canceller (NIC) to cancel Bluetooth interference occurring in IEEE 802.11b WLAN systems. The proposed NIC has a simple structure: an adaptive filter followed by a Rake receiver. The simulation results show that the proposed NIC can effectively cancel Bluetooth interference in an 802.11b receiver. Although an IEEE802.11b/Bluetooth framework is given as an example, the proposed NIC can be used in any spread spectrum system with frequency-hopping narrowband interference (FHNBI).
