Abstract: Doppler effects are compensated for in received wireless communication signals. In a receiver a first signal is received, that was transmitted by a transmitter at a first frequency f1 and that was received at a doppler-shifted first frequency f1? and a second signal, that was transmitted by said transmitter at a second frequency f2 and that was received at a doppler-shifted second frequency f2? is also received.
