Based on the minimum mean squared error (MMSE) between the data stream and the linear combiner output, a new multiuser detection (MUD) algorithm that combines space-time (ST) processing and antenna diversity on direct-sequence CDMA signals is proposed. The new ST-MUD algorithm does not require explicit estimation of channel and signaling information, as such it avoids any channel estimation error...
A novel deterministic direction-finding algorithm, which is based on a single snapshot of array measurement, is proposed. A combiner, which applies spatial-domain least-square, is first defined. The power pattern of the combiner output is then generated. The direction-of-arrival of each impinging source corresponds to a main lobe on the power pattern. By searching these main lobes, one can identify...
