Title: Jinho Ko - Innovator in FSK Signal Modulation
Introduction
Jinho Ko is a notable inventor based in Daejeon, South Korea. He has made significant contributions to the field of signal processing, particularly in the modulation and demodulation of frequency deviation keying (FSK) signals. His innovative work addresses critical challenges in achieving optimal modulation index and spectral efficiency.
Latest Patents
Jinho Ko holds a patent for a "Method and apparatus for modulating/demodulating an FSK signal." This invention presents a method and apparatus capable of overcoming the trade-off relationship between modulation index and spectral efficiency. The apparatus includes a channel selection-modulator, a phase locked loop, and an output unit. The channel selection-modulator modulates an FSK signal by setting a frequency channel to be used. The phase locked loop generates a desired output frequency 'fout' compared to a reference frequency 'f' by adjusting a frequency division ratio (N+n) with respect to the frequency of the modulated FSK signal. The output unit amplifies the FSK signal having the generated output frequency 'fout' and radiates the amplified FSK signal through an antenna. Each of the frequency channels is divided into two or more tones, with different frequency channels allocated between the tones.
