Abstract:One of the purposes of receive filtering in the Universal Mobile Telecommunication System (UMTS) terminal receiver is to provide channel selection selectivity. This enables the terminal to receive a desired signal in the presence of interfering signals. The worst case interference conditions in which an UMTS terminal still has to operate are defined by a number of conformance tests in the UMTS standard. The interference conditions in which the terminal has to operate in practice are however not always worst case. Based on the required number of operations it is determined when an adaptive digital receive filter is more computationally ecient than a Finite Impulse Response (FIR) receive filter in a terminal where a large part of the receive filtering is performed in the digital back-end. This turns out to be the case when the Adjacent Channel Interference (ACI) conditions are 10 dB or more
below worst-case.
