In this paper, we propose a frequency-domain iterative channel estimation scheme for training sequence aided single-carrier (TS-SC) block transmission using frequency-domain equalization (FDE). The proposed channel estimation consists of two steps. In the 1st step, the received training sequence having cyclic property is constructed for the frequency-domain channel estimation to obtain the instantaneous channel estimate. The improved channel estimate is obtained by simply averaging the instantaneous channel estimates over several blocks. The noise power is also estimated. In the 2nd step, the maximum likelihood channel estimation is carried out iteratively by using both the estimated symbol sequence and the training sequence. The bit error rate (BER) performance with the proposed frequency-domain channel estimation is evaluated by computer simulation. It is shown that the proposed channel estimation achieves a BER performance close to the perfect channel estimation. |
