Reducing PAPR using PTS Technique having standard array in OFDM
Journal Title: International Journal of Engineering, Science and Mathematics - Year 2012, Vol 2, Issue 4
Abstract
Orthogonal frequency division multiplexing is an attractive technique for modern wireless communication and has recently been focused in high-data-rate wireless communication research. However, high peak-to-average power ratio (PAPR) of the transmitted signal is a major disadvantage of OFDM. So far, numerous approaches have focused on the PAPR reduction. As one of these approaches, partial transmit sequence is effective and uncomplicated. This paper presents a standard PTS architecture for PAPR reduction of OFDM Signals by using the standard arrays Partial Transmit Sequences. The PTS method divides the input data block into disjoint sub blocks and recombines them by using weighting factors. Furthermore, such PAPR solutions are analyzed theoretically and compared.
