Abstract
An aspect of the present invention is the use of two criteria in channel estimation, e.g. a value related to the length of an estimated Channel Impulse Response (CIR) and a value related to a noise content of the received signal, e.g. a Signal-to-Noise Ratio (SNR). These parameters can be used for the post-processing algorithm. An advantage of the present invention is that it is much more robust against long channels and/or high noise contents in received signals. Additionally it has moderate implementation complexity.
