Transmit Diversity Gain in LTE

Transmit diversity gain can be used when transmitting broadcast information from multiple antennas. This effectively produces, by design, frequency diversity in the transmitter. The gain obtained from transmit diversity can…

MULTIPLE ANTENNA TECHNOLOGY IN LTE

The use of multiple antenna technology allows the exploitation of the spatial domain as another new dimension. This becomes essential in the quest for higher spectral efficiencies With the use…

BEAMFORMING in LTE

If some knowledge of the downlink channels of the different transmit antennas, (more specifically some knowledge of the relative channel phases) is available at the transmitter side, multiple transmit antennas…
