Latest Patents
One of Jacob Sheinvald's latest patents is titled "Code-division-multiple-access (DS-CDMA) channels with aperiodic codes - A method for channel estimation." This patent describes a method for estimating channel responses by receiving an input signal that results from a superposition of waveforms encoding symbols transmitted by multiple transmitters. Each transmitter modulates the symbols with a respective spreading code, and the input signal is sampled over an observation period to provide a sequence of complex samples. The processing of these samples allows for the estimation of the channel response for each transmitter.
Another significant patent by Sheinvald is "Enhancing CDMA multiuser detection by constraining soft decisions." This method involves receiving a complex input signal from multiple transmitters and sampling it over an observation period. The sequence of complex samples is then processed to determine soft decision values corresponding to the transmitted symbols. By constraining these values to a circle in a complex plane, the method enhances the accuracy of estimating the transmitted symbols.
