Hardware design of filter bank-based narrowband/wideband interference canceller for overlaid TDMA/CDMA systems
Description
An adaptive interference canceler, which we have proposed for the coexistence problem of TDMA/CDMA systems can jointly cancel both wideband interference (CDMA signals in terms of TDMA signals) and narrowband interference (TDMA signals in terms of CDMA signals). 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 "multiresolution analysis capability" of multirate filter bank. We describe an experimental system for the multirate filter bank-based narrowband/wideband interference canceler, and give the detailed hardware design of the canceler with fixed-point DSPs (digital signal processors).
