Abstract
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.
