Title: Innovations by Po-Hsiang Lan
Introduction
Po-Hsiang Lan is a prominent inventor based in Taipei, Taiwan. He has made significant contributions to the field of technology, particularly in the area of signal processing. With a total of 12 patents to his name, Lan has established himself as a key figure in innovation.
Latest Patents
One of his latest patents is a multi-tap decision feed-forward equalizer with precursor and postcursor taps. This innovative configuration provides a multi-tap Differential Feedforward Equalizer (DFFE) that has reduced noise and crosstalk characteristics compared to traditional Feedforward Equalizers (FFE). The DFFE utilizes decision outputs of slicers as inputs to a finite impulse response (FIR), which enhances performance by minimizing noise. The digital outputs from the tentative decision slicers are multiplied with tap coefficients, allowing for a more efficient implementation. The decisions made at the outputs of the tentative decision slicers are used in a FIR filter to equalize the signal, resulting in a lower bit-error-rate (BER) in the final stage compared to previous stages.
