Nonlinear precoding in code-division multiple access communication system |
摘要 |
<p>A method for preprocessing a spread-spectrum transmission, comprising the steps of:
receiving channel state information for multipath channels to K receivers, K ‰¥ 2;
precoding incoming K × 1 symbol vectors prior to transmission by
applying a first feedback filter to a previously-precoded vector, and subtracting from the incoming K × 1 symbol vector to cancel intersymbol interference, the first feedback filter generated using the channel state information; and
applying a second feedback filter and a feedforward filter, the second feedback filter and the feedforward filter arranged so as to use the channel state information to cancel multiuser interference along the multipath channels to the K receivers.</p> |
