| 摘要: |
| 在文献[4]采用不同扩频码和解扩码来降低高峰均功率比的基础上,通过仿真实验分析不同扩频码和解扩码对系统性能的影响。结果发现,使用不同的放频码和解扩码虽然确实能有效降低系统的PAPR,但是也在一定程度上增大系统的误码率。建议在采用这种方法降低PAPR时,必需兼顾PAPR的降低和对系统的误码率性能影响,才能使得系统的整体性能得到改善。 |

| Abstract: |
| We analyze the effect of the method to performance of system,which was proposed on reference based on using different spreading and dispreading codes to reduce peak-to-average power ratio (PAPR). The research results demonstrate that this method using different spreading and dispreading codes can reduce PAPR efficiently,but it also results in the degradation of bit error rate(BER) in some sense.In order to gain the whole amelioration of system,we must give attention to the effect to BER performance when we use this method to reduce PAPR. |
