- W2912321194 abstract "A new partial transmit sequence (new-PTS) scheme is illustrated in this study. The target behind it is to reduce the peak-to-average power ratio (PAPR) in an orthogonal frequency division multiplexing (OFDM) system. Despite its competitive attributes, the PTS technique is considered computationally expensive due to multiple inverse fast Fourier transforms (IFFT) and the need of a thorough investigation to find the optimal phase factor. The primary concern, thus, is to eliminate the IFFT blocks. In the present study, a remarkable strategy has been followed, mainly relying on analysing the available data in the random access memory. Additionally, the least PAPR value is calculated and its corresponding address is precisely determined; such an address is the side information to be sent to recover the users' original data at the OFDM receiver. Moreover, the effectiveness of the so-called complexity reduction of the new-PTS method is pointed out in order to limit the number of searches that are required to acquire the best PAPR performance, which significantly reduces the computational complexity overhead. Consequently, the numerical analysis and comparative study show the overall high performance, which the proposed PTS scheme offers in respect to both the bit error rate and PAPR reduction." @default.
