Title: The Innovative Contributions of Jitendra Rayala
Introduction
Jitendra Rayala is a notable inventor based in San Jose, CA, who has made significant contributions to the fields of digital signal processing and echo cancellation. With a total of 2 patents to his name, Rayala's work showcases his expertise and innovative thinking in technology.
Latest Patents
Rayala's latest patents include a digital signal processor featuring an inverse discrete cosine transform engine for video decoding. This invention involves a distributed arithmetic multiply/accumulate (MAC) unit designed for computing inverse discrete cosine transformations (IDCTs). The MAC unit consists of a first pipeline stage that performs dot products on sequential input data and a second pipeline stage that computes additions and subtractions of the dot products to produce sequential output data.
Another significant patent is an echo canceller that includes a frequency domain active region location estimator. This method and apparatus are designed to cancel an echo path by locating an active region for the subsequent application of a filter. The process involves acquiring a plurality of far-end signals and corresponding near-end signals, removing correlation within these signals, and applying gain control to achieve a uniform level. The stored data blocks are then processed to determine coefficients for a bank of adaptive filters, ultimately leading to the identification of the active region of the echo based on energy estimates.
