RELAY STATION, TRANSMISSION METHOD FOR RELAY STATION, AND COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18446976 titled 'RELAY STATION, TRANSMISSION METHOD FOR RELAY STATION, AND COMMUNICATION SYSTEM

Simplified Explanation

The patent application describes a relay station with antennas, wireless devices, and a controller to control the operation of the wireless devices. Each wireless device includes a receiver, an FIR filter, and a transmitter to process and transmit signals.

  • The wireless devices convert radio signals received by antennas into baseband signals.
  • An FIR filter in each device assigns a delay to the baseband signal.
  • The transmitter converts the filtered signal into a radio signal transmitted to the reception station.
  • The controller sets different delay amounts in the FIR filters of each wireless device to ensure unique delays for signals from different antennas.
      1. Potential Applications
  • Wireless communication systems
  • Relay stations in telecommunications networks
  • Signal processing technologies
      1. Problems Solved
  • Minimizing interference in wireless communication
  • Improving signal quality and reliability
  • Enhancing data transmission efficiency
      1. Benefits
  • Enhanced signal transmission performance
  • Reduced signal interference
  • Improved overall network reliability and efficiency


Original Abstract Submitted

A relay station comprises antennas, wireless devices corresponding to the antennas, and a controller to control an operation of the wireless devices. Each of the wireless devices includes a receiver to convert the first radio signal received by a corresponding antenna into a baseband signal, an FIR filter to assign a delay to the baseband signal; and a transmitter to convert a signal output from the FIR filter into a second radio signal transmitted from the corresponding antenna to the reception station. The controller sets a different delay amount in the FIR filter in each of the wireless devices so that the FIR filter assigns a delay, which is different from among the antennas, to the baseband signal input from the receiver in each of the wireless devices.
