  • Data transmisson system with a low peak-to-average power ratio based on distorting small amplitude signals
    Patent number: 5793797
    Abstract: An electronic data transmission system has a low peak-to-average power ratio by including a transmitter circuit which receives an input signal and in response generates a distorted output signal. This distorted output signal is generated by amplifying the input signal with one particular gain when the input signal is at a maximum magnitude which gives the distorted output signal a corresponding maximum magnitude, and by amplifying the input signal with a larger gain when the input signal is in a predetermined range below the maximum magnitude. The distorted output signal travels over a communication channel to a receiver circuit, which regenerates the input signal by amplifying the distorted output signal with a gain that is the inverse of the gain by which the distorted signal is generated.

  • Data transmission system with a low peak-to-average power ratio based on distorting frequently occuring signals
    Patent number: 5651028
    Abstract: An electronic data transmission system has a low peak-to-average power ratio by including a transmitter circuit which receives an input signal and in response generates a distorted output signal. This distorted output signal is generated such the output signal has a large magnitude when the input signal has a high probability of occurrence, and the output signal has a small magnitude when the input signal has a low probability of occurrence. The distorted output signal travels over a communication channel to a receiver circuit which regenerates the input signal by amplifying the distorted output signal with a gain that is the inverse of the gain by which the distorted signal is generated.
