Latest Patents
One of his latest patents is the "Equalizer mode switch." This apparatus is designed for automatically selecting between a standard decision directed mode and a soft decision mode in a decision feedback equalizer for receiving data signals. The equalizer provides a DFE output signal and includes a control input that responds to a control signal, which indicates whether to select the standard or soft decision mode. Additionally, it features a lock detector that provides a lock signal indicative of equalizer convergence.
Another significant patent is the "Concatenated equalizer/trellis decoder architecture for an HDTV receiver." This system processes High Definition Television signals by using the re-encoded trellis decoder output as an input to the feedback filter of the decision feedback equalizer. The design allows for hard or soft decision trellis decoding and accounts for latency associated with trellis decoding. The system offers performance improvements of between 0.6 and 1.9 decibels, with cascading two modules typically sufficient to achieve most of the potential performance enhancement.
