  • ROBUST PRECODING VECTOR SWITCHING FOR MULTIPLE TRANSMITTER ANTENNAS
    Publication number: 20140254715
    Abstract: Methods, apparatuses, and computer program products for robust precoding vector switching for multiple transmitter antennas are provided. One method includes defining, by a base station, a precoding vector switching (PVS) scheme for transmission of synchronization signals through multiple antennas comprising a plurality of pairs of cross-polarized antenna elements. The PVS scheme includes changing a direction pattern from co-polarized antenna elements for the first and for the second occurrence of the synchronization signals, and rotating a polarization from each of the pairs of cross-polarized antenna elements for the first and for the second occurrence of the synchronization signals.
