Abstract

We propose an adaptive interference canceler for the co-existence problem of TDMA/CDMA systems, which can jointly cancel both wideband interference (CDMA signals in terms of TDMA signal) and narrowband interference (TDMA signals in terms of CDMA signal). The canceler is implemented with a 63rd-order IIR-based multirate filter bank, so it can digitally process all the signals in baseband with less computational cost, and can efficiently cope with narrowband signals with various bandwidths (transmission rates), making full use of the “multiresolution analysis capability” of the multirate filter bank
