Channel delay spread estimation with subtraction of training symbol autocorrelation

摘要

In accordance with one embodiment of the invention, an estimation block (224) provides an estimated delay spread based on a received training sequence, said estimation block (224) comprising: a matched filter (226) to filter said received training sequence, a filter response correction unit (228) to subtract an ideal long training symbol autocorrelation function from a response of the matched filter, and a channel delay spread estimator (230) to provide the estimated delay spread based on the output of the filter response correction unit.
