Title: Innovations by Shridhara A Kudrethaya
Introduction
Shridhara A Kudrethaya is an accomplished inventor based in Cupertino, CA. He holds three patents that showcase his expertise in the field of signal processing and GPS technology. His innovative contributions have significantly advanced the capabilities of spread spectrum signal receivers and GPS systems.
Latest Patents
One of his notable patents is the "Correlator sum method for spread spectrum signal receivers." This invention provides systems and methods for faster acquisition and more stable tracking of spread spectrum signals with lower computational load requirements. Instead of relying solely on the Prompt correlator, his method utilizes the sum of the powers of all the correlators of a channel to enhance signal acquisition speed, resulting in a reduced Time-To-First-Fix (TTFF). Additionally, it improves the acquisition and tracking sensitivity of the receiver.
Another significant patent is the "Unassisted indoor GPS receiver." This invention enables GPS receivers to track very weak GPS signals, particularly in indoor environments, without assistance from an external server or network. The GPS receiver initially acquires and locks onto satellite signals outdoors to compute its position. It then tracks at least one satellite signal indoors to maintain acquisition parameters for quick signal acquisition. To conserve power, the receiver automatically enters a sleep state and periodically wakes up to maintain satellite signal tracking.
