Latest Patents

Ching-Yih Tseng holds a patent for an "Adaptive blind start-up receiver architecture with fractional baud rate sampling for full-duplex multi-level PAM systems." This invention presents a novel receiver architecture designed for full-duplex multi-level Pulse Amplitude Modulation (PAM) systems. The architecture employs an Analog-to-Digital Converter (ADC) with a sample rate flexibly specified as (N+1)/N baud rate, where N is an integer equal to or greater than 1. A fractional-spaced echo canceller is utilized to eliminate echo at the ADC output. The implementation of a fractional sampling rate higher than the baud rate allows for timing recovery in the digital domain, thus removing the need for complex analog phase selection circuits. The receiver is capable of fast, blind start-up through a decision feedback equalizer with a unity main tap and a soft level slicer. The timing phase is optimally located using a derivative channel estimator. Once the 'eye-open' condition is achieved, the channel equalization switches to a linear equalizer coupled with an error feedback equalizer to mitigate the error propagation problem associated with the decision feedback equalizer.
