Latest Patents
Hadjihassan's latest patents include a groundbreaking invention titled "Flash ADC receiver with reduced errors." This patent addresses the issue of symbol decoding errors at a receiver utilizing a flash analog to digital converter (ADC). By adjusting the reference voltage level of the ADC, the decoding error rate can be minimized when it exceeds a certain threshold.
Another significant patent is the "Method and apparatus for adjusting receiver voltage threshold and phase sampling point using FEC counts." This invention provides methods and apparatus for adjusting slicing parameters, such as voltage thresholds and phase sampling points, to recover binary signals from a transmitted signal. The bit error rate (BER) is modeled as a second-order polynomial of the slicing parameters, and the model is updated using a recursive least squares fit based on measurements from a Forward Error Correction corrected bits counter.
