Title: Omkar Pradhan: Inventor of a Self-Calibrating Correlating Receiver

Introduction

Omkar Pradhan is an inventor based in Pasadena, California, and is associated with the California Institute of Technology. His patent work concerns receiver circuitry designed to calibrate and correct imbalances between in-phase (I) and quadrature (Q) signal channels.

Latest Patents

Pradhan is named on one patent, titled “Self-calibrating correlating receivers.” The invention describes a circuit that processes I and Q signals through a Fourier transform, combines corresponding frequency-bin channels, and applies an inverse Fourier transform. It then correlates the resulting signals, transforms the correlation output, and compares a correlation term with zero. An error-correction circuit uses that comparison as feedback to tune the magnitude and phase of the I and Q channels. This approach is intended to help calibrate receiver channels automatically.
