Abstract
A signal analysis method is described. The signal analysis method includes the following steps. A first difference quantity is determined based on a first set of samples by a first polyphase filter, wherein the first set of samples includes at least two input samples. A second difference quantity is determined based on a second set of samples by a second polyphase filter, wherein the second set of samples includes at least two input samples, wherein the input samples associated with the second set of samples are time-shifted with respect to the input samples associated with the first set of samples. The first difference quantity and the second difference quantity are compared based on a predefined criterion. At least one timing parameter of the symbol sequence is determined based on the comparison of the first difference quantity and the second difference quantity. Further, a signal processing module is described.
