Method and device for identifying at least one communication channel with an incident signal

摘要

Method and device for identifying at least one communication channel with an incident signal Method for identifying within an incident signal at least one frequency communication channel, said incident signal being received on a wireless apparatus, comprising determining a power spectral density (PSD) of that incident signal and identifying said at least one channel from said PSD (203-207, 403-408). The said PSD determination comprises storing (201, 401) temporal samples of said incident signal received during a predetermined duration and performing a first Discrete Fourier Transform (DFT) processing on said stored samples (202, 402).
