Interference cancellation is a research area in communication systems and signal processing that focuses on mitigating or eliminating unwanted signals or noise that can interfere with the desired signals in a communication channel. This can improve the overall performance of wireless communications systems and increase the throughput and reliability of data transmission. Interference cancellation techniques often involve sophisticated algorithms and signal processing methods to separate and remove interference from the received signal. This area of research is particularly important in crowded or noisy communication environments, where multiple signals may be present simultaneously.
