ANALYSIS OF PAPR IN IFDMA SYSTEMS USING NORM TECHNIQUE

Abstract

Interleaved Frequency Domain multiple access (IFDMA) utilizes single carrier modulation and frequency domain equalization and has similar performance as of orthogonal frequency division multiple access (OFDMA) and has been adopted for the uplink communications in release 8 LTE. But it is sensitive to non-linear effects duo to the high peak-toaverage power ratio (PAPR) of the transmitted signal .The reduction in PAPR is required in order to achieve better BER performance and more power efficiency. This paper presents an Reduced maximum complexity Max Norm algorithm [1] for reducing the PAPR in IFDMA signals .This method does not require the transmission of the side information to the receiver, which improves the utilization of bandwidth. The result has been shown using complementary cumulative distribution function (CCDF) plot and also have been compared with PAPR of IFDMA signals without implementing RCMN technique and which shows that the PAPR of IFDMA signals with RCMN technique have lower PAPR compared to IFDMA signals without using RCMN technique
