Abstract

A method for automatically detecting cellular mobile channels of a certain cellular mobile standard and their respective center frequencies is described. A spectrum assigned to said cellular mobile standard is received via at least one receiving antenna. Said spectrum received is automatically analyzed by a detection system. A peak detection is performed during said automatic analysis in order to obtain a list of cellular mobile channels and their respective center frequencies for said cellular mobile standard. Further, a detection system is described.

Claims

1. A method for automatically detecting cellular mobile channels of a certain cellular mobile standard and their respective center frequencies, with the following steps:

receiving a spectrum assigned to said cellular mobile standard via at least one receiving antenna;

automatically analyzing said spectrum received by a detection system, wherein said spectrum received is analyzed by determining an absolute maximum in said spectrum received, and wherein said spectrum received is analyzed by determining a maximum threshold, said maximum threshold being defined by said absolute maximum and a predefined loss; and

performing a peak detection during said automatic analysis to generate a list of center frequencies for respective cellular mobile channels for said cellular mobile standard.

4. The method according to claim 1, wherein a step function depending on the frequency of said spectrum received is determined, said maximum threshold being used for defining said step function.

5. The method according to claim 4, wherein a correlation is done for a respective channel bandwidth of said cellular mobile standard and said step function.

6. The method according to claim 5, wherein said peak detection is done for said correlation.

7. The method according to claim 1, wherein a weighted list of potential center frequencies for said cellular mobile standard is generated.

8. The method according to claim 7, wherein said list of center frequencies is generated based on said weighted list of potential center frequencies for said cellular mobile standard.

9. The method according to claim 7, wherein at least one of said list of center frequencies and said weighted list of potential center frequencies is verified by an evaluation unit.

10. The method according to claim 1, wherein said list of center frequencies is displayed on a display.

11. The method according to claim 1, wherein said list of center frequencies is post processed by a post processing unit.

12. The method according to claim 1, wherein a predefined set of parameters with regard to said cellular mobile standard is used for automatically detecting said cellular mobile channels of said certain cellular mobile standard.
