ABSTRACT:
A signal evaluation apparatus, and method, for data reduction in the processing of signal values of a digital signal processing unit, for example, in a mobile communication system, wherein a block with k signal values is inventively stored in fixed decimal point format and a maximum value of the k signal values of the block is defined. Subsequently, the k signal values of the block are converted into floating decimal point format, whereby individual mantissas and a common exponent are determined for the converted samples. The data rate can be substantially reduced depending on the selected number of bits for the presentation of the mantissas and exponents. Advantageously, the block corresponds to the samples of a radio block or a part thereof.
