WebSep 28, 2024 · Using , the PAPR result of the proposed LDHT in Figure 5 perfectly agrees with earlier LDHT and outperform DCT, FWHT precoding and standard OFDM schemes by 3.8 dB, 5.8 dB and 6.0 dB, respectively; it performs similar to DFT precoded OFDM. These results make it quite attractive for DHT precoding to be included in the future … WebDec 4, 2024 · 3.3 Companded OFDM Signals. From Eq. (), the signal \( S_{p} \left( n \right) \) represents precoded OFDM signals, and PAPR of these signals is minimized up to the single-carrier system because of spreading input data symbols [].Recall that the phase of the signals is distorted by the DFT precoder. Without increasing the system complexity, the …
