Abstract: Since the inherent high envelope fluctuation characteristics of OFDM signals present a significant challenge in reducing energy consumption, it is crucial to minimize the range of the ...

Abstract: In this paper, a new non-linear companding technique, called "exponential companding", is proposed to reduce the high peak-to-average power ratio (PAPR) of orthogonal frequency division ...

Theory of how companding works: Suppose that we have a signed 16 bit linear sample in 2's complement math. The range of this sample can vary from -32768 to + 32767 in integer steps. Now lets put the ...
