A PAPR reduction scheme with residue number system for OFDM
The peak-to-average power (PAPR) is one of the main challenges in multicarrier transmissions. Aiming at reducing the PAPR, we propose a residue number system (RNS)-based OFDM parallel transmission scheme. The key idea of the proposed scheme is to utilize the parallel property of RNS to convert the input signals into the parallel smaller residue signals while utilizing the characteristic of RNS ...
متن کاملBelief Propagation Based Combined Decoding Scheme for LDPC-coded OFDM with PTS as PAPR Reduction
This paper proposes belief propagation based combined decoding scheme for low-density parity-check (LDPC)-coded orthogonal frequency-division multiplexing (OFDM) system with a peak-to-average power ratio (PAPR) reduction using the partial transmit sequence (PTS), which does not transmit PTS side information about the phase factors. Keywords— Belief Propagation (BP), Partial Transmit Sequence (P...
متن کاملPAPR Reduction Scheme with SOCP for MIMO-OFDM Systems
Combination of multiple-input multiple-output (MIMO) with orthogonal frequency division multiplexing (OFDM) has become a promising candidate for high performance wireless communications. However one major disadvantage of MIMO-OFDM systems lies in a prohibitively large peak-to-average power ratio (PAPR) of the transmitted signal on each antenna. In this paper we extend from SISO to MIMO systems ...
متن کاملPAPR reduction scheme with selective tone reservation for OFDM signals
In this paper, we propose a peak-to-average power ratio (PAPR) reduction scheme with selective tone reservation. In this scheme, the preset peak reduction tone (PRT) set would be divided into M PRT subsets that can generate M time-domain kernels. The differences of the slopes for the phase responses of the M timedomain kernels would be considered to design the M PRT subsets in reducing the PAPR...
متن کاملM-2m Mapping Scheme for Papr Reduction in Slm and Pts Based Ofdm Systems without Si
As discussed in chapter 3, selected mapping (SLM) and partial transmit sequence (PTS) are the two most popular distortion-less PAPR reduction techniques but both of them require the transmission of SI, with each OFDM symbol to recover the original OFDM signal. The transmission of SI not only reduces the effective data rate, but also degrades the error performance of the OFDM system, in case of ...
