<p>The device has a frequency transposition block (200) including a local oscillator (221) to produce an oscillator signal at frequency, a mixer (222) to mix digital and oscillator signals to deliver a baseband signal and an analog/digital converter (223) to convert orthogonal frequency division multiplexing (OFDM) or baseband signal into digital signal. A demodulation block (300) has a detection circuit (332) to detect a frequency shift of the digital signal and deliver a correction signal (cor) that is provided to the local oscillator to partially readjust frequency of the digital signal.</p> |
