Latest Patents

Sung Chan Cho holds a patent for a "Two-dimensional optical CDMA system, PN coded wavelength/time encoder and decoder therein." This invention discloses a CDMA optical system along with the encoder and decoder included within it. The time domain encoding means creates a time domain code that follows a sequence based on inputted data bits or a complementary code. The optical modulation means selectively outputs lights, which are incident upon it from the outside, to two output leads according to the chip bits of the time domain code or the complementary code. Furthermore, a wavelength domain encoding means encodes the light outputted from the first output lead into a wavelength domain sequence, transmitting the wavelength code to the base station. It also encodes the light from the second output lead into a complementary sequence of the wavelength domain sequence, transmitting the complementary code to the base station.
