  • Patent number: 7689124
    Abstract: Disclosed herein are a CDMA optical system and encoder and decoder included therein. Time domain encoding means creates a time domain code having a sequence according to inputted data bits or a complementary code which is complementary to the time domain code. An optical modulation means selectively outputs lights, in which the lights are incident upon the optical modulation means from the outside, to two output leads, respectively, according to chip bits of the time domain code or the complementary code. A wavelength domain encoding means encodes the light outputted from a first output lead of the optical modulation means to a wavelength domain sequence (two dimensional code), transmits the wavelength code to the base station, encodes the light outputted from a second output lead to a complementary sequence of the wavelength domain sequence, and transmits the complementary code of the two dimensional code to the base station.

  • Patent number: 6725042
    Abstract: A method for setting a protocol revision value for determining an environment of a service provided by a second base station by a mobile station during a handoff from a first base station to the second base station in an idle state in a mobile communication system including the first base station and the second base station neighboring the first base station, a service supported by the second base station being different from a service supported by the first base station. The mobile station receives an extended system parameter message (ESPM) from the second base station; compares a length of the received ESPM with a length of a preset ESPM; and sets a protocol revision value of the mobile station according to a protocol revision value included in the received ESPM, if the length of the received ESPM is equal to or longer than the length of the preset ESPM.
