Latest Patents
Stephan Weisser holds 1 patent for his invention titled "Clock recovery for band-limited optical channels." This patent describes a coherent optical receiver where the channel equalizer and the clock-recovery circuit are connected in a nested-loop configuration. The channel estimate generated by the equalizer is utilized to adjust the phase of the clock signal produced by the clock-recovery circuit. The design allows for the implementation of the channel equalizer using a bank of time-domain or frequency-domain FIR filters. In an example embodiment, the clock-recovery circuit is adept at tracking phase rotation in a frequency-dependent manner, thereby enhancing the clock tone through a Fourier transform applied to the squared absolute values of the equalized signals.
