Reducción del PAPR en la señal multiportadora OFDM-IM mediante la técnica de envolvente constante

Abstract

In this article, the envelope technique was evaluated constant for signal PAPR reduction OFDM multicarrier with modulation index, candidate for sixth-grade wireless technology generation. The results show that the application of the constant envelope technique based on Phase modulation allows a reduction of 9.28 dB for a probability distribution function complementary cumulative tion of 10−5. This will possible the use of this modulation in the new en- wireless turnstiles increasing their range since extends its use in the nonlinear regimes of the transmitter power amplifiers.
