Latest Patents

Rungeler holds a patent for "Adaptive equalization for recording systems using partial-response." This invention addresses the varying channel characteristics of magnetic-disk storage devices that change with track radius. The adaptive three-tap transversal equalizer he developed compensates for these variations effectively. The equalizer coefficients are updated using a method related to the recursive least-squares algorithm, which does not require multiplications, making it suitable for high-speed implementation. Computer simulations and measurements with a prototype have demonstrated that this adaptive equalizer can successfully compensate for variations in magnetic-disk channel characteristics.
