Hybrid-beamforming designs are developed by combining multiple array elements into subarray modules. A T/R module can be dedicated to multiple elements in the array; thus, the system will require ...

Thus, the precoding and combining is done in two stages. Because this approach performs beamforming in both digital and analog domains, it is referred to as hybrid beamforming. 5G MIMO array ...

Using this element, a fixed-beam 4 × 4 dual-polarized subarray is designed that maintains a bandwidth of 16.7% at 30 GHz with a maximum gain of 19.3 dBi and symmetrical radiation patterns. The ...

Fujitsu has announced it has built a prototype wireless unit, incorporating inter-subarray coding technology. This makes it possible to achieve data transmission in excess of 10Gbit/s, whilst ...

Fujitsu’s utilization of coding technology between antenna subarrays enables a low power 5G technology for the practical implementation of millimeter-wave high-speed communications Fujitsu ...
