Definitions

- Beams for transmission in mobile communication systems, that is, by sending signals spatially towards a specific direction, a higher antenna array gain can be achieved.
- Beams can be implemented by technical means such as beamforming.
- beamforming For example, in high frequency (HF) communication, an important direction is analog and digital hybrid beamforming. This can not only resist the loss caused by the transmission distance of high frequency signals, but also reduce the complexity. And hardware costs are controlled within an acceptable range.
- HF high frequency
- the transmitting end In a beam-based communication system, in order to obtain the beam gain, the transmitting end will collectively transmit signals in a specific direction, and the receiving end will adjust the receiving beam mode to obtain as much signal energy as possible.
