Resource Block Assignment to Reduce Peak to Average Power Ratio in Multi-User OFDM
This paper proposes the assignment of resource blocks (RBs) to reduce the peak-to-average power ratio (PAPR) of orthogonal frequency division multiplexing (OFDM) in a multi-user OFDM system. This system ranks the users according to the channel state information (CSI) for RB assignment. In our proposed technique, an RB is assigned to either the firstor second-ranked mobile station (MS) to minimi...
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...

متن کاملPeak-to-average power ratio in high-order OFDM
The problem of peak-to-average power ratio (PAPR) of high-order orthogonal frequency-division modulation (OFDM) is considered. Using results on level crossing of random processes, an upper bound on the probability that the PAPR of an OFDM signal will exceed a given value is derived. Numerical computations are used to show that this bound is tight for low-pass OFDM systems. The central limit the...
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...
