Abstract
Orthogonal Frequency-division multiplexing is an attractive technique for high-bit-rate communication systems. It has been widely used in modern wireless communication because of its high data rate, immunity to delay spread, its higher spectral bandwidth efficiency, robustness to frequency-selective fading channels and other advantages [10] and [17]. The PAPR problem in the OFDM system can be formulated for increase of PAPR, leads to severe intercarrier interference, out-of-band radiation, and poor bit error rate performance because of the nonlinearity of the high power amplifier, in the cellular networks such as in the LTE-Adv network. In this paper, we propose a method for reducing the PAPR in transmission chain an OFDM signal and reception for LTE-Adv network into taking account the parameters of the power amplifier. But also at the reception, we considered two signals: ideal OFDM signal and OFDM signal with noisy.
