A MIMO basestation mitigates an ongoing jamming attack while continuing to serve the legitimate user equipments. The signal processing for this takes place in a custom ASIC.

Short Description

Jamming attacks pose a critical threat to wireless communication systems. Multi-antenna (MIMO) wireless systems have the potential to mitigate such jamming attacks through signal processing. Methods for jammer mitigation are thus currently a hot research topic in wireless communication. Many different linear [1], [2] and non-linear (e.g., deep learning based [3]) jammer mitigation algorithms have been proposed. To be practically viable, such methods will ultimately have to be implemented in hardware (using FPGAs or, more likely, ASICs), since sofware-based signal processing will never support the data rates of modern wireless systems. To this date, however, there are no hardware implementations of jammer mitigation algorithms.

The goal of this project is to develop the first ASIC implementation of a jammer-mitigating signal processing algorithm. For this, the student will take a state-of-the art jammer mitigation algorithm and adapt it as an efficient VLSI implementation. The student will then synthesize this design and tape out a chip using CMOS technology.
