Patent ID: 7197280

Claim:
A method for searching for the carrier frequency f of a mobile radio transmitter in a mobile radio receiver, having the following steps: a) measuring two or more values e(k) of a variable which is characteristic of the spectral reception power at various discrete test frequencies f k , with the test frequencies f k differing by multiples of a step width frequency Δ and with f k being less than f k+1 for all measured values e(k) and e(k+1); b) searching for the maximum e(k max ) of the values e(k), with e(k max ) being associated with a specific test frequency f kmax ; and c) determining of an estimated value f′, which is characteristic of the sought carrier frequency f, from knowledge of the values of at least one value pair e(k 1 ) and e(k 2 ) where k 1 <k max <k 2 , and of the specific test frequency f kmax .
