BEAMFORMING TECHNIQUE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240259065 titled 'BEAMFORMING TECHNIQUE

The abstract describes a technique for performing beamformed transmission or reception on a radio channel. The method involves channel estimation, determining candidates for beamforming weights based on channel state, and selecting the resolution for computing the beamforming weights.

  • Channel estimation of the radio channel is performed to determine the channel state.
  • A list of candidates is generated for the frequency domain resolution of beamforming weights, each associated with a loss in terms of bit error rate (BER) depending on the channel state.
  • Beamformed transmission or reception is performed using the computed beamforming weights based on the channel state, with the resolution selected from the list of candidates based on the associated loss in terms of BER.

Potential Applications: - Wireless communication systems - 5G networks - IoT devices

Problems Solved: - Improving signal transmission quality - Enhancing data rates in wireless communication - Minimizing bit error rates

Benefits: - Increased reliability in communication - Enhanced performance in challenging environments - Optimal use of available resources

Commercial Applications: Title: "Advanced Beamforming Technology for Wireless Communication Systems" This technology can be utilized in telecommunications companies, network equipment manufacturers, and IoT device manufacturers to improve the efficiency and reliability of wireless communication systems.
