Abstract

A device for carrying out search procedures includes a memory for storing a digital received data sequence, and a memory storing a predetermined correlation data sequence. A correlation device has a first section, in which sequence elements of the received data sequence are correlated with sequence elements of the correlation data sequence. A variable number K of sequence element correlation results are summed in the second section, in order to form an accumulated correlation result.
