“…In addition, WP-PTS scheme is developed with same criteria as in C-PTS scheme except for the block function of Inverse Fast Fourier Transform (IFFT) is replaced with Inverse Discrete Wavelet Packet Transform (IDWPT). In comparison within the same graph, Rostamzadeh in his paper [5] also showed the profile of PAPR for WP-OFDM scheme of db5 using N = 128 and 64QAM using C-PTS scheme where he applied the number of subblock, V = 4.…”

“…It is highlighted in this paper that instead of separate transmission for between , conventional (C-PTS) PTS technique and re-known work in [5] the optimized data and the SI data, we are able to transmit both within a single frame, while the nature idea of minimizing the PAPR of the signals is remained and preserved. Further investigation should be done in order to reduce the degree of complexity of proposed scheme.…”

The Partial Transmit Sequence (PTS) scheme is magnificent in reducing the high peak-to-average power ratio (PAPR) in multicarrier modulation (MCM) signals. However, the scheme produces Side Information (SI) data as the result of optimization which reduces the high PAPR of the signals. The SI data must be transmitted along with the optimized information data over the channel. Due to this, we develop a design of embedding the SI data into the Wavelet Packet-based OFDM (WP-OFDM) frame and able to reconstruct the original information by utilizing a simple reconstruction technique at the receiver. This paper presents single main contributions: The Wavelet Packet-based PTS (WP-PTS) scheme with a unique approach of managing the SI data. The WP-PTS scheme is the combination of WP-OFDM system and conventional PTS scheme. In fact, WP-PTS scheme has similar structure as conventional PTS scheme except different signal transformation block is utilized. The PAPR performance of embedding SI data using WP-PTS scheme is compared with WP-PTS scheme under similar conditions. A PAPR profile of uncoded WP-OFDM signal is also included. Results show that the PAPR profile of WP-PTS scheme with embedding SI data has converged towards PAPR profile of WP-PTS scheme. The WP-PTS scheme with embedding SI data obtained 3.0dB improvement if compared to uncoded signal at 10 −4 of CCDF level with small lost in BER performance.

<p class="1">A novel method of Peak–to-Average–Power-Ratio reduction is presented in this paper using WPT for multi carrier modulationand Riemann matrix for phase sequencing in SLM. Wavelet Packet Multicarrier Modulation(WPM) is a betteralternative to the existing multicarrier transmission system,OFDM system which suffers from high PAPR.Further reduction in Peak to Average Power Ratio (PAPR)is achieved by using Wavelet Packet Modulation(WPM) with SLM technique. Classical SLM uses random phases for phase rotations which suffers from the additional load of transmitting SI(side Information) to receiver. So to overcome a novel method is proposed here which uses the principle of varying the phases of the subcarrier data block to be transmitted ,using rows of the normalised Reimann matrix as phase sequence vectors for the Selected Mapping (SLM)Technique. The generated WPM frame with minimum PAPR is selected and transmitted .The proposed system achieves a significant improvement in PAPR reduction over the OFDM-classical SLM and WPM-classical SLM.</p>

“…Among recent well‐known PAPR reduction techniques based on WP‐OFDM systems, the partial transmit sequence (PTS) technique is an attractive scheme because it can reduce PAPR without distorting signal orthogonality. In [11], a PTS scheme for a special multicarrier modulation (MCM) system, known as WP division multiplexing, was proposed using Daubechies 5 wavelet db 5. Another work [12] proposed a method based on pruning the full‐tree structure of WP modulation with the PTS scheme to reduce the number of nodes.…”

Partial transmit sequence (PTS) is an effective scheme to reduce high peak-to-average power ratio (PAPR) for multicarrier modulation (MCM) signal transmission systems. This approach produces side information (SI) data as a result of the MCM signal optimisation process. The generated SI data are required to be transmitted with the original data over the channel for successful data recovery at the receiver. An effective method for SI data transmission has not yet been identified and research is still ongoing. Hence, the authors introduce a technique that embeds SI data into the original data frame. In this study, a wavelet packet (WP)-based PTS (WP-PTS) scheme is selected as the MCM transmission method. The proposed scheme is called WP-PTS with embedded SI data. In addition, a suitable scheme for reconstructing the original data is developed. Simulation result shows that the PAPR performance of the proposed scheme improves by up to 2.5 dB at a complementary cumulative distribution function level of 10 −4 compared with the original WP-orthogonal frequency-division multiplexing system without the PAPR reduction scheme when the number of selected disjoint subblocks is 16.
