Patent ID: 7283600

Claim:
A process for detecting an initiation of a burst in a digital received signal r(v) during use of a digital reference signal p(v), said process comprising the following procedural steps: executing a correlation by formation of a cost function L(v 0 ) with a correlation function within a correlation interval dependent upon a time delay of the received signal r(v) relative to a bit offset or a chip offset v 0 , which is characterized by the reference signal p(v), whereby addends of the correlation function were multiplied by a frequency offset correction factor, namely e −j2πΔ{tilde over (f)}v , the frequency offset correction factor being characterized by a frequency offset Δ{tilde over (f)} of the received signal r(v) relative to the reference signal p(v); and seeking a maximum Max(L) of the cost function L(v 0 ) dependent upon the bit offset or the chip offset v 0 and upon the frequency offset Δ{tilde over (f)} whereby the maximum Max(L), following a carrying out of a Fourier Transform is sought in a frequency space.
