Low Complexity PTS Scheme for Reducing PAPR in OFDM Systems
In this paper, the PTS scheme generate alternative orthogonal frequency frequency division multiplexing (OFDM) signal sequences by multiplying all the time domain samples with phase rotating vectors to find an OFDM signal having the minimum peak-to-average power ratio (PAPR). However, it needs an exhaustive search which causes large computational complexity. In order to solve this problem, we p...
متن کاملLow Complexity SLM-Based PTS PAPR Reduction Scheme for OFDMA Uplink Systems
High peak to average power ratio (PAPR) is one of the main drawbacks of Orthogonal Frequency Division Multiple Access (OFDMA) systems. In this paper we will introduce a PAPR reduction scheme based on selected mapping (SLM) and partial transmit sequence (PTS) techniques. The deficiency for PAPR reduction in SLM is computational complexity. We investigate one of the low complexity SLM schemes and...
متن کاملLow-complexity Pts-based Schemes for Papr Reduction in Sfbc Mimo-ofdm Systems
The systems which have the high peak-to-average power ratio that is OFDM systems which degrades the performance of the amplifier. To overcome this, various distortion and distortion less algorithms are suggested. The Partial Transmit Sequence (PTS) is the technique that is distortion less which separates the sequences of input to the subsequences and selects minimize optimized PAPR in the signa...
متن کاملA Low Complexity Forward Error Correction for PAPR reduction in OFDM Systems
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...
متن کاملPAPR reduction scheme: wavelet packet-based PTS with embedded side information data scheme
Partial transmit sequence (PTS) is an effective scheme to reduce high peak-to-average power ratio (PAPR) for multicarrier modulation (MCM) signal transmission systems. This approach produces side information (SI) data as a result of the MCM signal optimisation process. The generated SI data are required to be transmitted with the original data over the channel for successful data recovery at th...
