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.
