Latest Patents
Two of Scott's latest patents illustrate his innovative contributions to the field:
1. **Data-directed frequency-and-phase lock loop** - This invention features a data-directed frequency-and-phase lock loop designed for an offset-QAM modulated signal. The system utilizes a first multiplier to multiply the signal by the output of a Voltage-Controlled Oscillator (VCO). The resulting output undergoes phase shifting, convolution, and is processed through multiple stages, ultimately feeding back to the VCO to establish a complete feedback loop.
2. **Combined trellis decoder and decision feedback equalizer** - This adaptive equalizer consists of a trellis decoder paired with a mapper and a decision feedback equalizer. Each tap receives input from different stages of the trellis decoder via the mapper, enhancing the system's performance in signal processing applications.
