These features include beam codebooks, multi-antenna beamforming training, beam refinement and beam tracking capabilities, and a quasi-deterministic channel model. Our work paves the way for a future implementation of the next generation wireless gigabit standard, IEEE 802.11ay. 展开 ...
HYBRID BEAMFORMING MULTI-ANTENNA WIRELESS SYSTEMSThis invention presents methods for MU-MIMO wireless communication systems comprising a BS with plural of antennas placed as a linear array or planar array, plural of UEs, for conducting two-level signal processing at the BS to reduce the system ...
In the HR 2/2 mode, the radiation pattern of the array had a wide beam width (both in the horizontal and vertical planes) and a large elevation angle. The horizontal simulation results showed that the antenna had a wide lobe in the complete frequency band, and the horizontal − 3...

SDA combines Huawei's unique adaptive power sharing and phase calibration technologies and innovative baseband beamforming mechanism, allowing antenna lobes to be adjusted through software configuration. This enables networks to provide outstanding performance by tapping into the huge bandwidth across the 1.8...
Let us remind here that studied multi-* nodes have a receive bandwidth of 40 MHz (hence multichannel; see Figure 9), multimode capability (802.11b or 802.11g received frames), and multiantenna structure. A first point is to verify available performance with multiantenna processing in this ...
