چکیده
Presently, orthogonal frequency division multiplexing (OFDM) as a multicarrier transmission system is widely used. Along with its advantages it has many disadvantages. One of its major drawback is high peak to average power ratio (PAPR). As with high PAPR the spectral efficiency of the high power amplifiers degrades. So it becomes necessary to maintain the efficiency of a wireless system to reduce the PAPR radio. To reduce the PAPR there are many techniques such as Clipping & filtering technique, selective mapping, tone reservation and partial transmit sequence. In this paper, the main focus is on clipping & filtering technique and partial transmit sequence. A general comparison between these two techniques has been done.

متن کاملSelective Tone Reservation Method for PAPR Reduction of Spatially Multiplexed OFDM Systems
Tone Reservation (TR) is one of the well-known methods for PAPR reduction of Orthogonal Frequency Division Multiplexing (OFDM) systems. In this method some sub-carriers are reserved for PAPR reduction and the symbols in these sub-carriers are selected such that the PAPR of the OFDM frame is minimized. In this paper, the iterative algorithm introduced earlier for TR method in single antenna OFDM...
