Latest Patents
William E. Ryan holds a patent for a Viterbi detector for class II partial response equalized Miller-squared. This novel circuit arrangement decodes Miller-squared (M²) encoded signals using Class II partial response (PR2) equalization techniques. The circuit utilizes a maximum-likelihood sequence estimator (detector) implemented by the Viterbi algorithm to minimize the probability of bit errors in a digital storage or transmission channel that employs M² encoding in combination with PR2 equalization. The PR2 equalization channel is modeled by a finite impulse response (FIR) filter, which is further modeled by a finite-state trellis diagram. This allows for the creation of a modified trellis when M² encoding is applied to the PR2 channel, providing the basis for implementing the detector according to the invention. He has 1 patent to his name.
