Latest Patents

One of his latest patents is titled "Frequency shaping and adaptive rounding for O-QPSK and MSK transmission in polar coordinates." This invention addresses phase modulation of polar coordinates in a transmitter of wireless signals, aiming to achieve high transmit power levels while meeting spectral mask and EVM requirements. The process involves mapping an input signal to a sequence of modulation frequencies, applying a digital frequency shaping filter, and utilizing an adaptive rounding algorithm to generate a reduced bit-width signal for transmission.

Another significant patent is "Systems and methods for gain and offset control." This method outlines a procedure for setting initial gain and offset for an automatic gain and offset controller (AGOC). It includes determining a gain level that prevents under-saturation or over-saturation of an input to an analog-to-digital converter (ADC) through a binary search over fixed gain levels. The method also involves updating the gain and offset in response to changes in signal levels.
