In this paper, we proposed an effective and unified transmit power allocation (TPA) scheme for the Singular Value Decomposition (SVD)-Assisted multi-user multiple-input multiple-output (MU-MIMO) downlink (DL) and uplink (UL) transmissions in the presence of imperfect channel state information (ICSI). The existing power allocation policies for the SVD-Assisted MU-MIMO system, such as equal power allocation...
This paper addresses the mean square error (MSE) uplink/downlink duality for the multiple input multiple output (MIMO) systems where imperfect channel state information (CSI) is available at the base station (BS) and mobile stations (MSs). The channel is modeled by incorporating antenna correlation at the BS. In contrast to the perfect CSI case where instantaneous MSE duality is considered, the average...
This paper studies power distribution in the downlink of a wireless CDMA network, where mobile stations (MSs) cooperatively relay traffic for their peer stations, and the destination station (DS) combines signals received from both the base station (BS) and the relay station (RS). Both the DS and the RSs transmit at the same frequency band. We consider both decode-and-forward (DF) and amplify-and-...
