Title: Innovations of Lakshmanan Gopishankar
Introduction
Lakshmanan Gopishankar is an accomplished inventor based in Portland, OR. He has made significant contributions to the field of technology, particularly in signal processing and 3D imaging. With a total of two patents to his name, Gopishankar continues to push the boundaries of innovation.
Latest Patents
Gopishankar's latest patents include a method for measuring channel signal to noise metric using constellation data. This invention describes systems and methods for estimating a Signal-to-Noise (S/N) ratio of an input channel carrying a QAM signal. A Modulation Error Ratio (MER) is calculated for the input QAM signal, utilizing only the centermost error values of a constellation of the input QAM signal. This modified MER accurately represents the S/N ratio of the input channel, allowing for precise determination using only the received I and Q components of the modulated QAM input signal itself. His second patent is a semi-automatic 3D stereoscopic disparity cursor. This invention provides a 'disparity cursor' for easily measuring disparity within a selected region of a 3D image under test. Users can place a window that defines the disparity cursor over a selected region of the 3D image using a mouse, keyboard, or other user-interface device. An average disparity value for the image segments contained within the window is then automatically calculated and reported to the user.
