DIGITAL PRE-DISTORTION AND ASSISTANCE INFORMATION SIGNALING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240283475 titled 'DIGITAL PRE-DISTORTION AND ASSISTANCE INFORMATION SIGNALING
The present disclosure provides techniques for digital pre-distortion (DPD) in wireless communication systems.
- A power amplifier (PA), a first DPD circuit, a second DPD circuit, and a transmitter are included in the apparatus.
- The first DPD circuit applies a first DPD to an input signal to generate a first resulting signal, which is then passed to the second DPD circuit.
- The second DPD circuit applies a second DPD to the first resulting signal to generate a second resulting signal, which is then amplified by the PA.
- The transmitter transmits the amplified second resulting signal to another apparatus.
Potential Applications: - This technology can be used in wireless communication systems to improve signal quality and efficiency. - It can be applied in 5G networks, IoT devices, and other wireless communication devices.
Problems Solved: - Addresses issues related to signal distortion and power efficiency in wireless communication systems.
Benefits: - Improves signal quality, reduces interference, and enhances overall performance of wireless communication systems.
Commercial Applications: - This technology has commercial applications in telecommunications, IoT devices, and other wireless communication industries. It can lead to more reliable and efficient communication systems, potentially increasing market competitiveness.
Questions about DPD: 1. How does digital pre-distortion technology improve the performance of power amplifiers in wireless communication systems? 2. What are the key differences between the first and second DPD circuits in the described apparatus?
Original Abstract Submitted
certain aspects of the present disclosure provide techniques for digital pre-distortion (dpd). an apparatus for wireless communication generally includes a power amplifier (pa); a first dpd circuit, a second dpd circuit, and a transmitter. the first dpd circuit is generally configured to: obtain an input signal; apply a first dpd to the input signal to generate a first resulting signal; and output the first resulting signal to the second dpd circuit. the second dpd circuit is generally configured to: obtain the first resulting signal from the first dpd circuit; apply a second dpd to the first resulting signal to generate a second resulting signal; and output the second resulting signal to the pa. the pa is generally configured to amplify the second resulting signal to generate an amplified second resulting signal. the transmitter is generally configured to transmit the amplified second resulting signal to a second apparatus.
