| Summary: | 碩士 === 國立中興大學 === 電機工程學系所 === 107 === Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier system capable of high-rate data transmission, and has many advantages. One of the important shortcomings is the Peak To Average Power (PAPR). In order to solve this problem, we have many methods such as SLM, PTS, etc. This article is mainly based on PTS.
Compared with the traditional partial transmission sequence (PTS), this paper uses tree and trellis structure of error correction (ECC), it can reduce the peak-to-average power ratio and search complexity either, and based on this, it is applied to data of larger length.
