Abstract
A method for compressing IQ measurement data obtained from a signal is described. Within the IQ measurement data, at least one block of IQ data is determined where redundancy of the respective data can be exploited. The IQ data of the at least one block is transformed into a transform domain where redundancy of the respective data can be exploited. Transform coefficients obtained in the transform domain are determined and assessed with regard to a pre-defined criteria so as to determine whether the transform coefficients comprise significant information. Only the IQ data assigned to transform coefficients having significant information is stored along with indices in the transform domain indicating where the respective transform coefficients occur in the transform domain.
