Abstract
The block coding scheme for OFDM, which is combining Golay complementary sequence with Reed-Muller code (GCRM) that limits PAPR up to 3 dB with error-correcting capability, has been introduced recently [J. A. Davis et al. (1999)]. However, the coding gain of GCRM cannot overcome ICI caused by frequency error in OFDM. In this paper, a new combined scheme of ICI self-cancellation [Y. Zhao et al. (2001)] [Y. Fu et al. (2002)] and GCRM code is proposed. This scheme is analyzed to show that it limits PAPR up to 6 dB and can compensate the nonlinear distortion by TWTA. It is also verified that for the low back-off value of TWTA, our scheme shows better performance than GCRM.
OFDM的分组编码方案结合了Golay互补序列和Reed-Muller码(GCRM),将PAPR限制在3db以内,并具有纠错能力,最近被引入[J]。A. Davis et al.(1999)。然而,GCRM的编码增益无法克服OFDM中频率误差带来的ICI。本文提出了一种新的ICI自抵消组合格式[Y。赵等(2001)[j]。Fu et al.(2002)],并提出了GCRM代码。分析结果表明,该方案可将PAPR限制在6 dB以内,并可通过TWTA补偿非线性失真。验证了由于TWTA的回退值较低,我们的方案比GCRM具有更好的性能。
