Belkacem Derras: Innovative Patents and Contributions at Seagate Technology Incorporated
Belkacem Derras is an esteemed inventor hailing from Longmont, CO, United States. With an impressive portfolio of 12 patents, his contributions have made significant strides in the field of adaptive MIMO channel equalization and detection, as well as blind partial response equalization.
One of Belkacem Derras' noteworthy patents is the "Adaptive MIMO Channel Equalization and Detection" method. This invention involves receiving a data signal over a multi-input multi-output (MIMO) channel and equalizing the signal using an adaptive equalizer circuit with an associated target. The method also includes estimating the taps of the equalizer circuit and the coefficients of the target, while imposing constraints on the target coefficients. Additionally, a similar minimization process is employed with a constraint imposed on whitening filter taps associated with a DDNP detector in the MIMO channel.
Another remarkable contribution by Belkacem Derras is his patent for the "Blind Partial Response Equalization" method and equalizer circuit. This innovation entails receiving a data signal over a channel and equalizing it using a blind partial response equalizer circuit, resulting in an equalized output. Notably, the estimation of partial response equalizer taps performed by the blind partial response equalizer circuit is independent of true channel input symbols and the detected symbols corresponding to the data signal.
