Latest Patents
One of his latest patents is a non-coherent frequency shift keying detection scheme. This invention addresses the challenge of capturing caller ID information while a voice-band modem operates in low power mode. The technique allows for the decoding of caller ID information transmitted by the telephone company, even when the computer is in sleep mode. It utilizes a threshold concept to measure the elapsed time between zero crossings of an FSK tone half cycle, enabling the capture of caller ID information effectively.
Another significant patent is the 4 x 4 dimensional block modulation code for a PAM-5 constellation. This method involves encoding and modulating bits of an information stream for high-speed communication systems. It divides the constellation of available points into zero parity vectors based on specific criteria, ensuring reliable data transmission with error correction. The systematic transmission of column vectors enhances coding gain, resulting in a low bit error rate.
