  • Patent number: 5745492
    Abstract: A speech freeze-out method in a communication system for transmitting speech information, which is sent from public telephone terminals (1) to a control center (5) through voice channels, from the control center (5) to a base station (8) through time division multiplexing radio frequency channels (6), and from the base station (8) to mobile stations (17) through transponders (13). The freeze-out processing is carried out when the control center (5) feeds the speech information to the time division multiplexing radio frequency channels (6) so that the number of transmission channels from the base station (8) to the transponders (13) is limited within an upper limit value.

  • Patent number: 5742909
    Abstract: A mobile communication fixed station 101 transmits significant data to a mobile station 103 (104) after holding the significant data for a predetermined time, and no significant data are transmitted to the mobile station during that time. When there are no significant data which are being held, the fixed station 101 transmits remaining time data indicative of the predetermined time to the mobile station, and no significant data are transmitted to the mobile station. When significant data is being held, time data indicative of the remaining time until the start of transmission of the significant data is transmitted to the mobile station in each slot from the time significant data occurs until the time the significant data is transmitted. The fixed station 103 , which has received the remaining time data stops receiving for a time interval corresponding to the remaining time.

  • Patent number: 5737082
    Abstract: An apparatus of measuring an electric signal comprises a laser device, optical elements, an electrooptic crystal, a photoelectric converter, and an electric circuit. The electrooptic crystal is selected from the materials in the type of having properties of changing its refractive index in the direction of its optic major axes and the direction of these axes by a function of an applied electric field. In the apparatus, the electrooptic crystal is placed in the electric field applied by an electric circuit under measurement. A laser beam emitted from the laser device is incident on the electrooptic crystal. A reflected light passed through the crystal is resolved into rays in two polarized direction. Each ray is subjected to a photoelectric conversion by passing through the photoelectric converter and exerted as an electric output. A differential signal of the electric output is defined as a measurement signal.

  • Patent number: 5694388
    Abstract: A CDMA demodulator which can follow fast fading, and reduce interference components from other users in the same cell. A received input spread signal is despread by an orthogonal filer (103). The orthogonal filer provides the input spread signal with successive delays each of an amount of 1/m of the chip interval of a spreading code, multiplies the delayed signals by tap coefficients, and sums up the products, thereby outputting the despread signal. Pilot symbols in the despread signal are compared with known pattern pilot symbols by an absolute phase estimator/phase error compensator (107) to obtain phase fluctuations of the received pilot symbols. The phase fluctuations are interpolated to each information symbol, and each information symbol is phase compensated. The phase compensated information symbols are decided by a decision block (108).
