Latest Patents

Akkalkot is associated with 1 patent: “Methods and Systems of Phase Aligning a Replica Carrier Signal for Use in Demodulating a Subcarrier Signal.” The invention describes a test and measurement system that transmits a modulated carrier signal to a proximity integrated circuit card, which load-modulates the signal to generate a modulated subcarrier signal. A test instrument acquires the signal and uses a phase-aligned subcarrier demodulator to process it. The demodulator detects commands and responses, identifies a correlation index for each response, and uses that index to adjust the phase of a replica carrier signal. It then down-converts each response and low-pass filters the modulated subcarrier signal to demodulate the response.

Career Highlights
