METHOD AND DEVICE FOR PRECODING A SEQUENCE OF TRANSMIT SAMPLES IN A MULTI-ANTENNA SYSTEM
Abstract:
A method (200) for precoding a sequence of transmit samples (s(t)) for transmission in a multi-antenna system includes the following steps: driving (201) the sequence of transmit samples (s(t)) through a cascade of memory blocks (H n H H n ) in accordance with a sampling time (t) of the sequence of transmit samples (s(t)) which memory blocks (H n H H n ) are based on the n-th channel estimate (H n ) to provide a series of power coefficient ( x ̃ ( t ) ) at exits of respective memory blocks of the cascade of memory blocks (H n H H n ); filtering (202) the series of power coefficients ( x ̃ ( t ) ) based on a filter function (∑ w i ) to provide a precoded transmit sample (y(t)); and upon estimation of a new channel matrix (H n+1 ), sliding (203) the memory blocks (H n+1 H H n+1 ) in the cascade of memory blocks together with the transmit samples (s(t)) of the sequence of transmit samples (s(t)) in driving direction while keeping the memory blocks (H n H H n ) to multiply the previously introduced transmit samples (s(t)).
