| Abstract: | GSM broadcast frequency detection is very important in the GSM cell phone localization and tapping application. In this article we introduce a GSM broadcast frequency detect method This method use digital down converter technology sample radio as I and Q samples, then use FFT to detect FCCH channel so that GSM broadcast frequency can be detected. |
