Abstract :
This paper studies the Doppler sensitivity of the link reciprocity provided by TDD in a MIMO (multiple-input multiple-output) system. Assuming perfect channel state information at the receiver, the knowledge at the transmitter is restricted to the channel probability distribution as well as its precise value at the uplink/downlink switch instant. Doppler sensitivity is studied by means of the rate loss within the time window spanned by two consecutive switch instants
