PAPR Analysis for OFDM Based on DT-CWT
نویسندگان
چکیده
This paper introduces a novel OFDM system base on dual – tree complex wavelet transform (DT-CWT). In the proposed scheme, DT-CWT is used in the place of FFT. The proposed scheme offers the best PAPR performance than the conventional OFDM and WPM systems at the expense of acceptable computational complexity without using any pruning techniques. The CCDF for the proposed scheme signal achieves about 3 dB improvements in PAPR over the traditional OFDM and WPM signals at 0.001 of CCDF. Keywords-OFDM; WPT; CWT; DT-CWT; PAPR.

متن کاملAn Efficient Scheme for PAPR Reduction of OFDM based on Selected Mapping without Side Information
Orthogonal frequency division multiplexing (OFDM) has become a promising method for many wireless communication applications. However, one main drawback of OFDM systems is the high peak-to-average power ratio (PAPR). Selected mapping (SLM) is a well-known technique to decrease the problem of high PAPR in OFDM systems. In this method, transmitter is obliged to send some bits named side informati...

Orthogonal Frequency Division Multiplexing (OFDM) is a useful technology in wireless communications that provides high-rate data transmission in multipath fading channels. The advantages of OFDM systems are the high spectral efficiency and strong resistance to frequency selective fading. In OFDM systems, a large number of sub-carriers are used to modulate the symbols causing the time-domain OFD...
