Is PAPR reduction always justified for OFDM?
نویسنده
چکیده
The justification of implementing PAPR reduction schemes in OFDM is discussed. Decreasing PAPR increases the efficiency of the linear power amplifier, yielding an increase in average power emitted and consequentially an increase in capacity. However, implementing a PAPR reduction scheme s such as Tone Reservation or Selective Mapping means a decrease in the payload bandwidth which causes a decrease in capacity. In this work capacity is analyzed to evaluate the efficiency of these PAPR reduction techniques.

Selective 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...

Orthogonal frequency division multiplexing (OFDM) has become a promising method for many wireless communication applications. However, one main drawback of OFDM systems is the high peak-to-average power ratio (PAPR). Selected mapping (SLM) is a well-known technique to decrease the problem of high PAPR in OFDM systems. In this method, transmitter is obliged to send some bits named side informati...

In this paper, a Peak to Average Power Ratio (PAPR) reduction technique in Orthogonal Frequency Division Multiplexing (OFDM) systems is proposed. This technique uses error correction capability of channel coding to reduce the PAPR.The coded bits at the input of OFDM modulator are separated into two groups of the Most Significant Bits (MSB) and the LeastSignificant Bits (LSB). The bits are mappe...
