Latest Patents

Cesar holds a patent for "Skew compensation based on equalizer coefficients." This invention involves a receiver that applies a calibration method to compensate for skew between input channels. The receiver skew is estimated by observing the coefficients of an adaptive equalizer, which adjusts the coefficients based on the time-varying properties of the multi-channel input signal. The skew is compensated by programming the phase of the sampling clocks for the different channels. Additionally, during real-time operation, channel diagnostics are performed to automatically estimate differential group delay and other channel characteristics based on the equalizer coefficients. This is achieved using a frequency averaging or polarization averaging approach. Framer information can also be utilized to estimate differential group delay that is an integer multiple of the symbol rate. Furthermore, a DSP reset may be performed when substantial signal degradation is detected based on the channel diagnostics information.
