  • System for transmitting radio signals from mobile terminals to provide space diversity for uplink signals via geostationary communication satellites
    Patent number: 5839053
    Abstract: The invention concerns a system for transmission of spatial diversity radio signals via a geostationary main communication satellite and one or more auxiliary satellites "colocated" in the same orbit. The distance between an auxiliary satellite and the main satellite is in the range from 200 km to 400 km. The system includes conventional bidirectional transmission links between terrestrial mobile terminals and the main satellite and between the latter and a terrestrial station. Additionally, unidirectional transmission links are provided between the auxiliary satellites and the main satellite. Applications include a mobile communication service with portable terminals via a geostationary satellite.

  • Method and system for performing transmission of digital data by coding bit information into the shape of a pulse and decoding the bit information from the shape of the pulse
    Patent number: 5583892
    Abstract: Digital information is transmitted by generating coded signals in the form of pulses on the basis of binary digital information and decoding the coded signals into the binary digital information, the pulses being coded in the time domain and being of at least two distinctly different shapes with respect to their numerical amplitude variation along the time axis of the pulses, the pulses comprising two bits of information in each pulse having energy one, but coded in the way that one bit of information is in the polarity and one bit in the shape, or two bits are in the shape.

  • High-speed staged decoder/quantizer
    Patent number: 5487075
    Abstract: A symbol-level pipelined structure for parallel systolic decoding of block codes which is a layered processor structure including a number of layers equal to the code length and each layer is adapted to decode the component codes of a concatenated code in sequence. The structure described provides efficient high rate decoding operation with an associated low cost and low hardware complexity.
