Abstract
In this paper, we focused on the method of peak-to-average-power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) systems, proposing a upper bound of peak-to-mean-envelope-power ratio (PMEPR) when the number of sub-carrier is different. We want to compare it with improved partial transmit sequence (PTS) and selective mapping (SLM) techniques. The objective is that predicting the PAPR maximum range with our proposed PMEPR upper bound by the simulation result of comparing the PMEPR performance and upper bound value. Due to these algorithms we compared have excellent performance, we analyze their computational complexity under the condition that these algorithms meet our upper bound so as to evaluate that these improved methods are suitable for practical application. Therefore, it is easy to determine the performance and practicability of a PAPR reduction method by using PMEPR upper bound in this thesis.
