Latest Patents

Keun-Mok Kim 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 for use. 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 with the generated output frequency 'fout' and radiates the amplified signal through an antenna. Each frequency channel is divided into two or more tones, with different frequency channels allocated between the tones.
