Peak 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...
متن کاملPeak-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 کاملThe use of interleaving to reduce the peak-to-average power ratio of an OFDM signal
An interleaver based technique for improving the Peak-to-Average Power Ratio (PAP) of an orthogonal frequency division multiplexing (OFDM) signal is presented. For this technique, K-1 random interleavers are used to produce K-1 permuted sequences from the same information sequence. PAPS of the permuted sequences and the original information sequence are then computed using of K oversampled FFTs...
متن کاملReducing the peak to average power ratio in OFDM systems
High peak to average power ratio of the transmit signal is a major drawback of OFDM systems. After defining the PAPR and analyzing its statistical properties, some of the most representative PAPRreduction techniques available in the literature are reviewed in detail. Several methods have been proposed to reduce the peak power of OFDM signals. In this paper the effectiveness of some recently pro...
