In this paper, a new suboptimal tone reservation (TR) algorithm with fixed phase rotation method based on Constant Amplitude Zero Auto-Correlation (CAZAC) sequence is proposed to reduce peak-to-average power ratio (PAPR) in multicarrier code division multiple access (MC-CDMA) systems. To decrease tone searching complexity of TR method, CAZAC sequences is utilized as initial tone candidates. To reduce searching time and remain excellent PAPR reduction performance, fixed phase rotation method is applied for the phase optimization of tone sequence to find final sub-optimal tone signals. In order to maintain average transmission power, additional constraint on the power of tone signals is supposed. Simulation results shows, by using CAZAC sequence as initial tone candidates and fixed phase rotation method for phase optimization, considerable PAPR reduction efficiency can be achieved accompanying with reduced computational time and system complexity compared with the traditional TR method.

“…Several newly proposed power amplifiers have the potential to work with high PAPR signals, such as Doherty amplifiers [9,12,17], but at the moment these technologies are at an experimental stage. Hence, several methods for reducing PAPR in OFDM-based systems have been proposed; such as pre-coding methods [2,4], probabilistic algorithms [9,18], and non-linear expanding and compressing methods [9,18].…”

Artículo de publicación ISIAs the demand for better performance increases in next-generation networks, such as 5G technologies, more efficient modulation techniques are required. In this work, we evaluate the performance of the improved parametric linear combination pulses (IPLCP) in orthogonal frequency division multiplexing (OFDM) based systems. OFDMbased systems are very sensitive to frequency offset errors, and are characterized by producing high peak-to-average power ratio (PAPR) values. The IPLCP is evaluated in terms of average inter-carrier interference power, average signal to interference power, PAPR, and bit error rate. Theoretical and numerical simulations show that the IPLCP pulse performs well in OFDM-based systems in comparison to other existing pulses

Peak-to-average power ratio (PAPR) plays an important role in the design of wireless communication systems because a high PAPR decreases the efficiency of the power amplifier. A new family of Nyquist pulses was derived by applying a linear combination between two Nyquist pulses. The proposed Nyquist pulses are utilized for pulse shaping to reduce PAPR. The investigated pulses are characterized by a new design parameter (p), giving an additional degree of freedom to minimize PAPR for a given roll-off factor α. While keeping the same bandwidth, the frequency responses of the proposed filters are unique with different values of the parameter p. Simulations showed that the optimum proposed pulse shaping filters provide better performance in PAPR reduction compared to those of the RC filter and other existing filters evaluated in various systems.
