Title: Wayne E Bretl: A Pioneer in Adaptive Channel Estimation and Robust Digital Communication

Introduction: Wayne E Bretl is a notable inventor based in Grayslake, IL, with a commendable record of 36 patents to his name. His innovative contributions primarily focus on adaptive low complexity channel estimation and robust digital communication systems, which have significant applications in mobile communication technologies.

Latest Patents: Among his recent achievements, Bretl has developed two noteworthy patents. The first is an "Adaptive Low Complexity Channel Estimation for Mobile OFDM Systems." This invention introduces an adaptive low complexity minimum mean square error (MMSE) channel estimator tailored for Orthogonal Frequency Division Multiplexing (OFDM) systems amidst mobile channels. By partitioning sub-carriers into windows—optimized according to channel model mismatch error (MME)—the complexity of the estimator is notably reduced. Three variants of the adaptive windowed MMSE (W-MMSE) estimators were proposed, showcasing innovative adaptations based on estimated signal-to-noise ratios (SNR) and channel model selection, thereby enhancing the robustness of real-time estimation.

The second patent, "Robust Digital Communication System," represents a groundbreaking approach to the reordering and transmission of data. In this system, robust VSB data is rearranged through interleaving methods before being multiplexed with ATSC data for efficient transmission to a receiver. The functioning of the receiver is designed to optimize processing by discarding unnecessary data types based on receiver specifications, thus ensuring a streamlined communication process.
