FRACTIONAL BAND SELF-INTERFERENCE CANCELLATION FOR FULL-DUPLEX COMMUNICATIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240204976 titled 'FRACTIONAL BAND SELF-INTERFERENCE CANCELLATION FOR FULL-DUPLEX COMMUNICATIONS
Simplified Explanation: The patent application describes a method for a user equipment (UE) to identify fractional bands within a bandwidth associated with full-duplex (FD) communication, sample signals within these fractional bands, estimate self-interference cancellation (SIC) coefficients based on the sampled signals, and perform SIC for the FD communication.
Key Features and Innovation:
- UE identifies fractional bands within a bandwidth for FD communication.
- Signals are sampled within these fractional bands.
- SIC coefficients are estimated based on the sampled signals.
- SIC is performed for the FD communication based on the estimated SIC coefficients.
- Sampling may be done at a rate lower than a threshold.
- An auxiliary hardware path with an auxiliary ADC may be used for sampling.
- Sampling may involve decimation or rotation.
Potential Applications: This technology can be applied in wireless communication systems, particularly in improving the performance of FD communication by reducing self-interference.
Problems Solved: The technology addresses the challenge of self-interference in FD communication systems, which can degrade signal quality and overall system performance.
Benefits:
- Enhanced signal quality in FD communication.
- Improved system performance.
- Reduction of self-interference for better communication reliability.
Commercial Applications: Potential commercial applications include telecommunications equipment, wireless networks, and IoT devices that rely on efficient communication systems.
Prior Art: Readers can explore prior research on self-interference cancellation techniques in wireless communication systems, particularly in the context of FD communication.
Frequently Updated Research: Stay updated on advancements in self-interference cancellation methods and technologies in wireless communication systems for potential improvements in FD communication.
Questions about FD Communication: 1. How does self-interference affect the performance of FD communication systems? 2. What are the key challenges in implementing self-interference cancellation techniques in wireless communication?
Original Abstract Submitted
