Abstract

We discuss the co-existence problem of DS-CDMA and TDMA systems where both systems share the same frequency band to improve the spectral efficiency. We propose a complex multirate filter bank (CMRFB)-based adaptive notch filtering technique for the DS-CDMA system, which can observe the received signal with different frequency resolutions at the same time, and easily form the most suitable notch filter for rejecting the TDMA signal
