  • Multiplex transmission system wherein analog signal is transformed to base band, random-transformed and superimposed on dispersed signal points in vector signal space
    Patent number: 6226302
    Abstract: A transmitter has a power calculation unit for calculating the power of a signal. A maximum value detection circuit determines a maximum value of an output of the power calculation unit, and a floating point transformation circuit changes an output of the maximum value detection circuit into a floating point representation. A significant bit extracting circuit extracts significant bits from an output of the floating point transformation circuit and outputs the significant bits as the transmitting signal.
