Method and apparatus for channel equalisation with estimation of the channel impulse response length

摘要

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. <IMAGE>
