ABSTRACT:
A hardware apparatus (10) for conditioning pilot symbols for channel estimation in a mobile radio comprises a time-division multiplexed low-pass filter unit for filtering the received pilot symbols. The time-division multiplexed low-pass filter unit comprises, between its input and its output, a feedback path which can be switched in and which can be used to implement a plurality of filter stages in a time-division multiplexed arrangement.
