Summary

The objective of the proposed research is to develop adaptation techniques for energy-efficient digital baseband processors in GPS acquisition and adaptive beamforming applications. Three techniques are presented: (1) an adaptive compressive sampling GPS correlator that reduces acquisition energy by 4.7x–51x in 65 nm CMOS, (2) a beamspace MVDR algorithm that replaces O(N³) matrix inversion with O(N log N) FFT-based operations, and (3) a gradient-descent-based beam tracker with adaptive step size and update-period control, validated in 16 nm and 28 nm CMOS implementations. Together, runtime adaptation to signal conditions delivers significant energy savings without sacrificing the digital baseband processing performance.
