Comparative Study of Channel Codes for OFDM System and Judgement for Batter Peak to Average Power Ratio (PAPR)

2013 International Conference on IT Convergence and Security (ICITCS), 2013
Orthogonal Frequency Division Multiplexing (OFDM) system is used for the reducing almost every kind of interference in any communication system. For designing OFDM system need to use FFT and IDFT phenomena of signal processing, in this work mainly concern to improve peak to average power ratio for this system because this system is multicarrier system,

Peak to Average Power Ratio (PAPR) reduction in OFDM for a WLAN network using SLM technique

2011 3rd International Conference on Electronics Computer Technology, 2011
Orthogonal 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.

Reducing peak-to-average power ratio (PAPR) using partial transmit sequence in OFDM systems

7th International Multi Topic Conference, 2003. INMIC 2003., 2005
OFDM is a multicarrier system supporting high data rate transmission and generally requires no equalization at the receiver, making it simple and efficient. However, a drawback of this system is the large peak-to-average-power ratio (PAPR) of the transmit signal, which makes its straightforward implementation quite costly.

C2. Progressive Image Transmission over OFDM System with Minimum Peak-to-Average Power Ratio (PAPR)

2013 30th National Radio Science Conference (NRSC), 2013
A modified Orthogonal Frequency Division MuItiplexing (OFDM) system for robust progressive image transmission is proposed in this paper. A joint sOUfce-channel coder (JSC C ) is employed in the modified OFDM system. The set partitioning hierarchical trees (SPTHT) used as SOUfce code, and The Low-Density Parity-C heck (LDPC ) used as a channel coder ...

Performance Analysis of Peak to Average Power Ratio (PAPR) Reduction Techniques in OFDM System for Different Modulation Schemes

2018 4th International Conference on Electrical Engineering and Information & Communication Technology (iCEEiCT), 2018
With the increasing demand for high power efficiency, robustness to multipath delay spread and high transmission speed, OFDM has become one of the most promising techniques for next generation wireless communication systems. However, high peak to average power ratio is a major limitation of OFDM system which makes the overall system less effective ...

Peak to Average Power Ratio (PAPR) Minimizing Techniques for Helical Interleaved OFDM System

Perspectives in Communication, Embedded-Systems and Signal-Processing - PiCES, 2017
Orthogonal frequency-division multiplexing (OFDM) is a multi-carrier, multi rate, multi symbol, frequency division multiplexing transmission system. In which a single high data rate stream is divided in to a number of low data rate streams. High spectral efficiency due to orthogonal subcarriers is the major advantage of this system.
