Title: Edward B. Loewenstein: Innovator in Modulation Quality Measurements

Introduction

Edward B. Loewenstein is a prominent inventor based in Austin, TX, known for his contributions to the field of modulation quality measurements. With a total of 7 patents to his name, he has made significant advancements in the analysis and measurement of signal quality in various devices.

Latest Patents

Loewenstein's latest patents include innovative techniques for determining modulation quality measurements of devices under test (DUT). One of his notable inventions involves receiving a modulated signal from a source multiple times and transmitting each received signal to both a first vector signal analyzer (VSA) and a second VSA. These analyzers demodulate the signals to produce error vectors, which are then used to perform cross-correlation calculations. This process results in an averaged cross-correlation measurement that serves as a basis for determining modulation quality.

Another significant patent focuses on the determination of uncertainty measures for estimating noise power spectral density. This system utilizes successive data acquisitions from noise signals appearing in two channels to compute cross (power) spectral densities. The averaged spectral density is then smoothed in the spectral domain, providing an effective estimate for noise power spectral density. The invention also includes methods for calculating statistical error bounds based on the effective number of averages.
