结合频域均衡方法的单载波OFDM（SC-OFDM）技术作为传统OFDM的替代传输技术最近受到了很多关注。与传统的OFDM技术相比，SC-OFDM技术可以在误比特率性能和峰均功率比（PAPR）方面获得更好的性能。SC-OFDM还具有通过采用自适应调制方法来提高信道容量的潜在能力。针对SC-OFDM信号自适应调制方法引入所需的接收噪声比估计问题，提出了一种新的估计方法。本文还提出了各种性能的建议SC-OFDM与自适应调制方法相比，传统的OFDM。
The single carrier OFDM (SC-OFDM) technique in conjunction with frequency domain equalization method has recently received a lot of attention as the alternative transmission technique to the conventional OFDM. The SC-OFDM technique can achieve the better performance in bit error rate performance and peak to averaged power ratio (PAPR) as compared with the conventional OFDM. The SC-OFDM has also a potential capability to improve the channel capacity by employing the adaptive modulation method. This paper proposes a novel estimation method for the received CNR of SC-OFDM signal, which is required in the introduction of adaptive modulation method. This paper also presents various performances of the proposed SC-OFDM with adaptive modulation method as comparing with the conventional OFDM.
