Phase noise estimation and suppression for single carrier SDMA uplink
Phase noise can severely impair transmission, especially in uplink space division multiple access (SDMA) scenarios. We derive a soft-decision-directed phase noise estimation and compensation algorithm in combination with iterative block decision feedback equalization (IBDFE) for uplink SDMA single carrier systems, such as those proposed in the 3GPP-LTE standard. The algorithm generalizes earlier algorithms for non-SDMA (single-user) systems. It is shown by simulation to be effective and relatively simple to implement.
