| 抄録(和) | Recently, multi-user multiple-input multiple-output (MU-MIMO) systems are widely studied. In these systems, spatial precoding techniques are commonly used for inter-user interference mitigation. However, these techniques require perfect knowledge of downlink channel state information (CSI) on the transmitter which is hardly achieved in a high mobility environment. One possible approach for this environment is the implementation of a collaborative interference cancellation (CIC) technique. In this technique, collaborating mobile stations (MSs) share their receive signals and can be regarded as one station equipped with many antennas. To obtain efficient signal-exchanges between collaborating users, user selection can be implemented to select C users from N available users. In this paper, a user selection scheme suitable for a QRM-MLD algorithm is proposed. Numerical results obtained through computer simulations show that the proposed scheme is able to provide an equal diversity compared to N users collaboration with a feasible computational complexity. |
