| Title | Self-interference Cancellation Techniques for Wideband Receivers |
| Summary | .Receivers are widely used in modern radio-frequency (RF) systems, including radars, satellites, telecommunications, and electromagnetic warfare equipment. At this juncture, wideband receivers have become a practical reality due to advancements in analog-to-digital converter (ADC) technology that have improved both bandwidth and resolution. Nonetheless, the broad spectrum exposure faced by ADCs in wideband receivers makes them susceptible to self-interference signals from nearby friendly transmitters. The presence of high-power interference signals can potentially saturate the ADC, rendering both the ADC and the receiver inoperable. It is therefore imperative to mitigate these interference signals and protect wideband receivers. This project aims to investigate advanced self-interference cancellation (SIC) techniques, such as adaptive interference cancellation, and state-of-the-art self-interference cancellation involving passive suppression, analog cancellation, and digital algorithms. These techniques will be designed to significantly enhance the performance and reliability of wideband RF receivers in the presence of self-interference signals from a friendly transmitter. The proposed techniques will be demonstrated as a proof-of-concept in synergy with an RF-ADC in challenging, highly-dynamic operating environments. Optionally an IC schematic will be designed and tested. |
