PRE-EQUALIZATION USING BEAMFORMING FUNCTIONALITY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18252089 titled 'PRE-EQUALIZATION USING BEAMFORMING FUNCTIONALITY

Simplified Explanation

The patent application describes a method, network node, and customer premises equipment for pre-equalization using beamforming functionality in a hybrid fiber cable network. Here is a simplified explanation of the abstract:

  • The method involves estimating the uplink channel of a hybrid fiber cable network by using reference signals received from consumer premises equipment.
  • The downlink channel is determined by taking the inverse of the uplink channel estimate.
  • A downlink signal is mapped to multiple layer-specific signals.
  • Beamforming weights are applied to the layer-specific signals to generate layer-specific downlink signals.
  • The layer-specific downlink signals are summed to produce a frequency-compensated downlink signal for transmission over the hybrid fiber cable network.

Potential applications of this technology:

  • This technology can be used in hybrid fiber cable networks to improve the quality and reliability of communication signals.
  • It can be applied in various industries that rely on high-speed data transmission, such as telecommunications, internet service providers, and broadcasting.

Problems solved by this technology:

  • The method addresses the challenge of estimating and compensating for channel impairments in a hybrid fiber cable network.
  • It improves the accuracy of signal transmission by pre-equalizing the uplink and downlink channels.

Benefits of this technology:

  • By using beamforming functionality, the method enhances the performance of the hybrid fiber cable network.
  • It allows for efficient transmission of data, resulting in improved communication quality and reliability.
  • The technology can potentially increase the capacity and speed of data transmission in hybrid fiber cable networks.


Original Abstract Submitted

A method, network node and customer premises equipment for pre-equalization using beamforming functionality are disclosed. According to one aspect, a method in a network node includes estimating an uplink channel of a hybrid fiber cable network using references signals received from consumer premises equipment, determining a downlink channel using an inverse of the uplink channel estimate, mapping a downlink signal to a plurality of layer-specific signals, and applying beamforming weights to the layer-specific signals to produce layer-specific downlink signals, and summing the layer-specific downlink signals to produce a frequency-compensated downlink signal for transmission over the hybrid fiber cable network.
