Title: The Innovations of William F. Schreiber
Introduction
William F. Schreiber is a notable inventor based in Cambridge, MA, with a remarkable portfolio of 13 patents. His work primarily focuses on advancements in television transmission systems, showcasing his expertise in encoding and signal processing technologies.
Latest Patents
Among his latest patents, Schreiber has developed a television transmission system using spread spectrum and orthogonal techniques. This innovative apparatus encodes a television production signal for transmission, which includes a first input signal carrying a first class of data and a second input signal carrying a second class of data. The second class of data requires a higher-quality transmission than the first class. The first stage of the system generates multiple serial samples of the output sample stream, while the second stage combines the input signals to produce an intermediate sample stream. This process includes a Discrete Fourier Transform (DFT) module that generates a parallel output stream, ultimately creating a frequency division multiplexed (FDM) output signal.
Another significant patent involves a two-stage spread-spectrum system for transmitting a coded TV signal. This system differentiates between components requiring near-perfect transmission and those for which imperfect transmission is acceptable. The first stage determines the signal-to-noise ratio (SNR) of the second components, while the second stage nullifies the effects of multipath in the transmission channel. The output is then modulated on a carrier to generate a transmission signal.
Career Highlights
Schreiber has had a distinguished career, contributing to significant advancements in television technology. He has worked at the Massachusetts Institute of Technology, where he has been involved in groundbreaking research and development projects.
Collaborations
