抄録(英) | In this paper, we investigate the capacity maximization problem for uplink spatial division multiple access (SDMA)/single carrier frequency division multiple access (SC-FDMA), under imperfect channel conditions. In fact, we improve our previous work and introduce a pilot assisted estimation method along with a sub-optimal power projection method based on users' spatial correlation, which chooses the users for each resource block (RB). We assume a single-input multiple-output (SIMO) scheme with correlation at receive antenna. Numerical analysis verifies that the proposed scheme improves the SE considerably at a target defined fairness level. We also investigate the effect of variations of different system design parameters, i.e., RB size, number of receive antenna, etc, on the system spectral efficiency, when channel state information is not perfect. |
