DYNAMIC CONTROL OF POWER AMPLIFIER BACK OFF FOR AMPLIFY AND FORWARD REPEATERS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17817617 titled 'DYNAMIC CONTROL OF POWER AMPLIFIER BACK OFF FOR AMPLIFY AND FORWARD REPEATERS
Simplified Explanation
The patent application describes a method and apparatus for dynamically controlling the power amplifier back off for repeaters. The apparatus uses a channel model to simulate the transmission channel between a receiver and a transmitter. It performs a peak-to-average power ratio (PAPR) reduction on the received signal to generate a signal with reduced PAPR. This signal is then passed through an inverse channel model to generate an output signal with reduced PAPR at the input of the receiver.
- The apparatus uses a channel model to simulate the transmission channel between a receiver and a transmitter.
- It performs PAPR reduction on the received signal to generate a signal with reduced PAPR.
- The reduced PAPR signal is then passed through an inverse channel model to generate an output signal.
- The output signal has reduced PAPR at the input of the receiver.
Potential applications of this technology:
- Wireless communication systems
- Cellular networks
- Satellite communication systems
- Radio frequency (RF) transmitters and receivers
Problems solved by this technology:
- High peak-to-average power ratio (PAPR) in signals transmitted over a channel
- Power amplifier back off control for repeaters
Benefits of this technology:
- Improved signal quality by reducing PAPR
- Enhanced efficiency of power amplifiers
- Increased capacity and coverage in wireless communication systems
- Reduced interference and improved signal-to-noise ratio
Original Abstract Submitted
Method and apparatus for dynamic control of power amplifier back off for repeaters. The apparatus uses a channel model to model a first signal at a channel output. The channel model models a channel between a receiver and a transmitter. The apparatus performs a PAPR reduction on the first signal at the receiver to generate a second signal having a reduced PAPR. The apparatus inputs the second signal through an inverse channel model to generate an output signal. The apparatus outputs the output signal to the receiver, such that the PAPR of the output signal is reduced at an input of the receiver.
