Training and data transmission phases: (1) Estimation phase: the parameters h ω, i, j [ s ] are first estimated at each Rx side during T e slots. (2) Feedback: the Gaussian vector is fed back to the transmitter during T f slots. vector. (3) Channel reconstruction: the Tx reconstruct the channel and adapt itself according to the feedback information. (4) Data transmission on parallel time-frequency channels.
