Peak-to-Average Power Ratio Reduction Techniques for OFDM Signals
Orthogonal frequency division multiplexing (OFDM) has been adopted as a standard for many modern wireless applications requiring high data rate due to bandwidth efficiency, resistance to frequency selective fading and simple digital realization using IFFT/FFT operations. However, physical implementation of the OFDM system suffers from several difficulties. One of the major limitations of OFDM i...
متن کاملPeak to Average Power Ratio Reduction of Ofdm Signal by Combining Clipping with Walsh Hadamard Transform
Wireless communications have been developed widely and rapidly in the modern world especially during the last decade. Orthogonal Frequency Division Multiplexing (OFDM) has grown to a popular communication technique for high speed communication. Besides of the advantages, one of main disadvantage of OFDM is high peak to average power ratio (PAPR). In this paper, a PAPR reduction method is propos...

متن کاملPeak-to-average power ratio reduction of an OFDM signal using data permutation with embedded side information
The use of a set of "xed permutations has recently been proposed for peak-to-average power ratio (PAR) reduction of an OFDM signal [ I ] . Sending the identity of the used permutation to the receiver reliably is critical in this method. This paper presents the use of data permutation with embedded side information (SI) to reduce the PAR of an OFDM signal. SI is coded using a simple forwarderror...
متن کاملPeak to Average Power Ratio Reduction of OFDM Signal byCombining Clipping with Discrete Cosine Transform-II
Orthogonal Frequency Division Multiplexing (OFDM) is a very attractive digital transmission method developed to meet the increasing demand for higher data rates in communications which can be used in both wired and wireless environments. OFDM consist of large number of independent subcarriers, as a result of which the amplitude of such a signal can have high peak values. High peak to average po...
