Coding Schemes Applied to Peak-to-Average Power Ratio (PAPR) Reduction in OFDM Systems
2008 International Wireless Communications and Mobile Computing Conference, 2008High PAPR of the transmitted signal is a major drawback in the OFDM systems. In this paper, coding schemes are proposed to reduce high PAPR One is using parity check coding scheme, and the other is using selected mapping (SLM) applied scheme. With parity check coding scheme, the parity information is used to expand the signal space.

Abstract Due to the evolution of mobile phone technology which enables the use of Internet, the demand for data rates has increased tremendously. Therefore, current 4G-LTE (long-term evolution) technology needs to be replaced in near future. Hence, currently possible solutions for 5G technology are heavily investigated.

Peak-to-Average-Power-Ratio (PAPR) Reduction Methods with Wavelet Transform in MIMO-OFDM
IETE Journal of Research, 2017ABSTRACTThis study is based on the comparison of the results with an analysis method recommended for the Peak-to-Average-Power-Ratio (PAPR) reduction methods. This is one of the most significant problems in the Multiple Input–Multiple Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems.

One of the potential technologies for a future wireless network is filtered-OFDM (F-OFDM). The capacity to handle numerous asynchronous sub-band transmissions is necessary in order to accommodate the diversity of services. However, multicarrier transmission systems with multiple subcarriers transmit signals with high Peak-to-Average Power Ratios (PAPR).

Peak to Average Power Ratio (PAPR) reduction in OFDM for a WLAN network using SLM technique
2011 3rd International Conference on Electronics Computer Technology, 2011Orthogonal Frequency Division Multiplexing (OFDM) is a spectrally efficient multicarrier modulation technique for high speed data transmission over multipath fading channels. OFDM modulation schemes offer many advantages for multicarrier transmission at high data rates over time dispersive channels, particularly in mobile applications.

Peak to average power ratio (PAPR) reduction in OFDM systems
International Multi Topic Conference, 2002. Abstracts. INMIC 2002., 2002Summary form only given, as follows. One of the main limitations of OFDM systems is that it exhibits high Peak to Average Power Ratio (PAPR). It is desirable to reduce it as high PAPR causes saturation in power amplifiers thus leading to inter-modulation products among the sub carriers.

In VLC system, increase in data rate leads to inter symbol interference (ISI). It is desired to reduce the high ISI using suitable modulation technique for high rate data traffic. Orthogonal frequency division multiplexing (OFDM) is an efficient modulation format to alleviate ISI effect.

One of the major drawbacks of OFDM is its high peak-to-average power ratio (PAPR) which can result in poor power efficiency and serious distortion in the transmitter amplifier. Tone reservation (TR) is a technique designed to combat this problem by reserving a number of sub-carriers (tones) in the frequency domain to generate a cancellation signal in ...
