Abstract
Orthogonal frequency division multiplexing (OFDM) is used to achieve the high-speed data transmission over fading channel. However, the main disadvantage of OFDM system is the high peak-to-average power ratio (PAR). This paper proposes a novel scheme based on convolution coding scheme and multiple signal representation (MSR) method which can be used for PAR reduction. Since the proposed scheme does not require the additional bit for PAR reduction, the proposed scheme provides the same code-rate as the conventional convolution coding scheme. Simulation results show that the proposed scheme reduces the PAR value while its BER performance is almost the same as the conventional convolution coding scheme. © 2007 IEEE.
