METHOD AND APPARATUS FOR PROCESSING SIGNALS IN A COMMUNICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17908677 titled 'METHOD AND APPARATUS FOR PROCESSING SIGNALS IN A COMMUNICATION SYSTEM
Simplified Explanation
The present disclosure describes a method and apparatus for self-interference cancellation in a wireless communication system. The method involves the following steps:
- Truncating a signal based on a detection window, where the signal includes a receive signal and a self-interference signal associated with a transmit signal. The length of the detection window is shorter than the symbol length.
- Performing self-interference channel estimation using the truncated signal and a first reference signal carried by the transmit signal. The first reference signal has a comb structure in the frequency domain.
- Performing self-interference cancellation based on the transmit signal and the estimated self-interference channel.
Potential applications of this technology include:
- Wireless communication systems where self-interference cancellation is required, such as full-duplex communication systems.
- Systems where accurate self-interference channel estimation is crucial for efficient cancellation, such as cognitive radio systems.
The problems solved by this technology are:
- Inter-symbol interference caused by timing misalignment, which can affect the accuracy of self-interference channel estimation. The method reduces this influence by truncating the signal based on a detection window.
- Self-interference in wireless communication systems, which can degrade the quality of received signals. The method provides a solution for canceling self-interference and improving overall system performance.
The benefits of this technology include:
- Improved accuracy of self-interference channel estimation, leading to more effective cancellation of self-interference.
- Enhanced quality of received signals by reducing self-interference, resulting in improved system performance.
- Simplified implementation of self-interference cancellation, making it more practical for use in various wireless communication systems.
