Advanced Antenna Systems,Transmit diversity and Beamforming in Wimax Advanced Antenna Systems The WiMAX standard provides extensive support for implementing advanced multiantenna solutions to improve system performance. Significant gains in overall…
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…
Currently, beam forming is only applicable for TDD version of LTE. The time synchronous version of LTE TDD on uplink and downlink also makes the implementation of beam forming more…
Multiple antennas in LTE may also be used to transmit the same signal appropriately weighted for each antenna element such that the effect is to focus the transmitted beam in…
