Radio receiver having a multipath equalizer
Abstract:
A radio receiver has a multipath equalizer that includes a filter and a coefficient estimator. The filter provides a reconstructed signal by applying a transfer function including a reflection coefficient and a delay coefficient to a multipath radio signal. The coefficient estimator adapts the reflection coefficient and the delay coefficient in response to a deviation in magnitude of the reconstructed signal from a normalized value. In one form, the filter evaluates the transfer function by truncating it to eight terms. In another form, the filter includes a delay line having delay elements for storing samples of the multipath radio signal received both before and after a current sample. In yet another form, the multipath equalizer further includes a normalizer that receives the multipath radio signal and provides a normalized multipath radio signal having a normalized magnitude to an input of the filter.
