PAPR, OFDM, Tone Reservation


Orthogonal frequency-division multiplexing (OFDM) has been considered for many high-speed wireless applications. Indeed, the orthogonal properties among subcarriers of OFDM lead to high spectral efficiency and excellent ability to cope with multipath fading environment. However OFDM systems have two major drawbacks: high peak-to-average ratio (PAPR) due to summing up of large number of subcarriers data together and inter-carrier interference (ICI) because the orthogonal properties are easily broken down byfrequency offset errors caused by oscillator inaccuracies. In this thesis, a coding technique is proposed to reduce both drawbacks. The scheme has tightly bounded PAPR and good error correction capability while reducing ICI significantly. The proposed technique is based on Tone Reservation.
