Comparative Study of PAPR Reduction Coding Techniques
نویسندگان
چکیده
There are many benefits of utilizing OFDM like robustness and high spectral efficiency against ISI but still there are some disadvantages. The main problem that arises in OFDM systems is high PAPR. There are many techniques available for reduction of PAPR like tone reservation (TR), clipping and filtering, partial transmit sequence (PTS), active constellation scheme, interleaving and selected mapping (SLM). Clipping and filtering are the easiest techniques but they are not suitable when large number of sub-carriers are present. The most common techniques used for PAPR reduction are PTS and SLM. PTS and SLM algorithms have achieved good performance in PAPR reduction..

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...

Orthogonal Frequency Division Multiplexing (OFDM) is one well-known scheme, which has recently become a preferred choice for parallel-data-transmission which reduces the influence of multipath fading and avoids the use of complex equalizers. However, an OFDM signal has a large peak-to-average power ratio (PAPR), which can result in significant distortion when transmitted through a nonlinear dev...
