Abstract:
1. A method for synchronizing a receiver including identifying a preamble in a frame, where the preamble has a preamble length 1, comprising: storing m data items received in succession; dividing the m data items into n portions, where the data items in each portion have respectively been received at successive times and where m and n are natural numbers and the following applies to m and n: m>n, m>1, n>1; respectively correlating the n portions to expected values to form component correlation results; respectively delaying the component correlation results, with at least two component correlation results being delayed by different lengths; combining the delayed component correlation results to form a total correlation value; and determining whether the m received data items contain the preamble of a frame based on the total correlation value, for synchronizing the receiver, wherein the processes of delaying the component correlation results and of combining the component correlation results are performed multiple times, wherein the processes of delaying the component correlation results differ in terms of the length of the delays, and the processes of combining the component correlation results involve a multiplicity of total correlation results being produced, and it is established that the m received data items contain the preamble of a frame if at least one of the total correlation results illustrates that the preamble is contained in the m received data items.
