Abstract

Thanks to relay network having the advantage of diversity and signal covering, lots of researches that require perfect channel estimation on relay network is undertaken. The superimposed training technique can estimate both the channel between source and relay and the channel between relay and destination pretty well. However, with orthogonal frequency division multiplexing (OFDM) being widely used, peak-to-average power ratio (PAPR) must be concerned. In this work, we apply a coding scheme based on Golay complementary sequences and Reed-Muller (RM) Codes into the system to reduce PAPR. Simulation results show that the proposed scheme does well in PAPR reduction.
基于叠加训练中继网络的Golay互补序列和Reed-Muller码PAPR约简
由于中继网络具有分集性和信号覆盖性的优点,对中继网络进行了大量需要完善信道估计的研究。叠加训练技术既能很好地估计源与中继之间的信道,也能很好地估计中继与目标之间的信道。然而,随着正交频分复用技术(OFDM)的广泛应用,峰值平均功率比(PAPR)问题必须引起人们的关注。在这项工作中,我们采用基于Golay互补序列和Reed-Muller (RM)码的编码方案来降低系统的PAPR。仿真结果表明,该方案具有较好的PAPR降低效果。
