Latest Patents

Hsu holds a patent for a "Polyphase filter with stack shift capability." This invention is a discrete Fourier transform (DFT) filter bank designed with stack shift capability, which can function as both an analyzer and a synthesizer. The filter is implemented as a polyphase filter, incorporating a complex modulator that multiplies input signals by a complex modulator. To maintain real coefficients for the polyphase filter, these coefficients are modulated by a DFT twiddle factor. This innovative approach significantly reduces hardware requirements, exemplified by the need for only eight selectable negators in an 8 phasetap filter, compared to traditional DFT filter banks.
