Abstract
A radio communications method includes carrying out, by a transmitter, transmission operations that include generating digital transmission signals carrying symbols to be transmitted and having a predefined time length; and transmitting a radio frequency signal carrying, in successive, non-overlapped time frames or slots having the predefined time length, the digital transmission signals generated. The method further includes carrying out, by a receiver, reception operations that include receiving the radio frequency signal transmitted by the transmitter; processing the received radio frequency signal to obtain a corresponding digital incoming signal; applying an oversampling operation to the digital incoming signal thereby obtaining an oversampled digital incoming signal; detecting successive, non-overlapped time frames/slots with the predefined time length in the oversampled digital incoming signal; and, for each detected time frame/slot, estimating respective symbols carried by the oversampled digital incoming signal in the time frame/slot with a predefined reception matrix incorporating a predefined Kalman filter.
