A system for amplifying a transmitted signal is provided. The system includes a receiver that receives the transmitted signal and generates a conducted signal from the transmitted signal. A non-linear oscillator, such as a synchronous oscillator that is operating in a borderline stable condition, is connected to the receiver. The non-linear oscillator receives the transmitted signal from the receiver and amplifies the transmitted signal without modifying the frequency of the transmitted signal, or its relative phase. The amplification by a non-linear oscillator causes the signal to be amplified relative to the noise, thus improving the signal-to-noise ratio.
