Title: Steve Xuefeng Jiang: Innovator in Signal Processing Technologies
Introduction
Steve Xuefeng Jiang is a prominent inventor based in Fremont, CA. He has made significant contributions to the field of signal processing, holding a total of 3 patents. His work focuses on developing advanced technologies that enhance communication systems.
Latest Patents
One of his latest patents is a limiter-based analog demodulator. This invention includes a phase detector that utilizes a decimator to process digitized in-phase and quadrature signals. The decimator operates at a rate that is a multiple of the symbol rate, allowing for efficient signal processing. Additionally, it features a burst detector to identify bursts in the output, a carrier offset block to determine offset angles, and a rotator for generating a rotated signal. An equalizer is also included to perform coherent demodulation of the rotated signal.
Another notable patent is the method and apparatus for a transmission signal up-converting filter. This invention employs a digital up-sampling converter (DUSC) that receives a signal input from a digital signal processor (DSP). The DUSC feeds a Square Root Raised Cosine (SRRC) filter, which provides table look-up of filter coefficients for multiple symbol spans. The output is then converted to an analog signal by a digital to analog converter (DAC) and processed through a low-pass analog filter before being delivered to an RF transmitter.
