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.
