This paper aims to developing a simulation model of Partial Transmit Sequence (PTS) Technique based on modified PTS blocks of Orthogonal Frequency Division Multiplexing (OFDM) systems. As Traditional PTS technique need side information for transmitting, so it increases its complexity. Partial transmit sequences (PTS) is an effective technique to reduce the peak-to-average power ratio (PAPR) of orthogonal frequency division multiplexing signals. However, the modified conventional partial transmit sequence (PTS) technique requires an exhaustive searching over all the combinations of the given phase factors, which results in the computational complexity increases exponentially with the number of the sub-blocks, so it is difficult to achieve in practical system. Most of the research in recent years has been focused on reducing the peak-to-average power ratio (PAPR) of the orthogonal frequency division multiplexing (OFDM) system, which is the most popular technology for multicarrier communication. Among all the proposed schemes, Modified PTS is one of the most effective ways to improve PAPR performance, but it results in high computational complexity.
