ELECTRONIC DEVICE AND METHOD FOR OBTAINING REVERSE SIGNAL AND FEEDBACK SIGNAL IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18188106 titled 'ELECTRONIC DEVICE AND METHOD FOR OBTAINING REVERSE SIGNAL AND FEEDBACK SIGNAL IN WIRELESS COMMUNICATION SYSTEM

Simplified Explanation

The patent application describes an electronic device that includes various components such as a digital pre-distortion (DPD), a digital-to-analog converter (DAC), a power amplifier (PA), and more.

  • The device includes a feedback system that uses a first coupler to obtain a feedback signal from the output of the power amplifier.
  • A circulator is used to obtain a reverse signal, which is a reflection of the output of the power amplifier.
  • A transmission filter is included in the device, and a second coupler is used to obtain a filter-feedback signal from the output of the transmission filter.
  • The device also includes an antenna for transmitting and receiving signals.
  • An analog-to-digital converter (ADC) is used to convert a composite signal, which includes the feedback signal, filter-feedback signal, and reverse signal, into a digital composite signal.
  • A separation circuit is included in the device to separate the digital composite signal into individual digital signals for the feedback signal, filter-feedback signal, and reverse signal.
  • A pulse inter-modulation cancellation (PIMC) circuit is used to process the separated digital signals along with an input signal of the DPD, in order to obtain processed digital signals for the feedback signal, filter-feedback signal, and reverse signal.
