Title: Gregory Stephen Ellard: Innovator in Signal Processing Technology
Introduction
Gregory Stephen Ellard is a notable inventor based in Binfield, GB. He has made significant contributions to the field of signal processing, particularly through his innovative patent related to maximum likelihood sequence estimation.
Latest Patents
Ellard holds a patent titled "MLSE before derotation and after derotation." This invention includes an equalizer or a receiver that factors detected symbols transmitted over a transmission channel into a magnitude portion and a repetitive phase portion. The receiver generates modified tap weights by multiplying the repetitive phase portion by tap weights representative of the channel. These modified tap weights are convolved with bits of possible states to generate possible transmitted symbols. A maximum likelihood sequence estimation is performed on these symbols, comparing each possible transmitted symbol to a received symbol to generate an MLSE detected symbol. The detected symbol is then multiplied by a rotating vector to produce a decoded symbol. In an alternate embodiment, a received symbol from the sequence of received symbols is multiplied by a rotating vector prior to performing the maximum likelihood sequence estimation.
