Abstract (in Japanese) (See Japanese page) 
(in English) This paper investigates the average block error rate (BLER) performance of turbo frequency domain equalizer (FDE) using iterative decision-directed channel estimation (IDDCE) for discrete Fourier transform (DFT)-precoded Orthogonal Frequency Division Multiple Access (OFDMA). Computer simulation results show that improvement in the required average received SNR satisfying the target average BLER is saturated at the iteration times of = 2 regardless of modulation scheme. We also shows that the IDDCE using only feed-forward FDE based on MMSE criterion at each iteration of turbo FDE is effective in improving the average BLER of turbo FDE. Moreover, we clarify that the effect of IDDCE is obtained when the operating region in the average received SNR is lower than approximately 15 dB for turbo FDE.
