| Abstract(in English) | The single carrier OFDM (SC-OFDM) technique has been received a lot of attention as the alternative technique to the conventional OFDM method. The SC-OFDM technique has much better performance in the PAPR as compared with the conventional OFDM. However, the SC-OFDM has a difficulty in the estimation of channel frequency response in the time varying fading channel as compared with the conventional OFDM. Although the channel estimation method for OFDM which employs the pilot subcarriers in the frequency domain can be used for the SC-OFDM, the PAPR performance would degrade relatively due to the insertion of pilot subcarriers in the frequency domain. This paper proposes a time domain channel estimation method of using the time domain training sequence by using the maximum likelihood (ML) method which can achieve the better BER performance without degradation of PAPR performance in the time varying fading channel. |
