Latest Patents

Among his latest innovations is a remarkable patent titled "Radio receiver with local oscillator modulation." This invention features an antenna subsystem that can effectively receive an analog desired signal alongside noise and interference through a communication channel. The desired signal contains modulated encoded digital information. The system includes a local oscillator modulation subsystem that generates a modulated local oscillator (LO) to optimize the symbol signal-to-noise ratio of the decoded digital information. This optimization considers various factors including the desired signal, expected interference and noise, and the capabilities of the digital signal processor (DSP) to filter out the modulated LO. The invention culminates in a mixer that blends the received signal with the modulated LO, followed by a converter that transitions the mixed signal from analog to digital. Ultimately, the DSP effectively removes the modulated LO and decodes the desired signal's encoded digital information.
