Interleaved frequency-division multiple-access (IFDMA), a special kind of single-carrier frequency-division multiple-access (SC-FDMA), with frequency domain equalization (FDE) is attracting much attention because of its peak-to-average power ratio (PAPR) property and frequency diversity gain. FDE requires accurate channel estimation. In the case of fast time varying fading channel, decision directed channel estimation (DDCE) is effective. However, in IFDMA, amplitude of each subcarrier may fluctuate depending on the combination of information data symbols, then estimation accuracy may degrade. In the literature, the method to flatten frequency spectrum by multiplying information data sequence by random phase sequence is proposed. However, complex transmitter and side information are needed in the method. We propose more simple and effective method in which the use of DDCE is adaptively controlled. The effect of the proposed method is evaluated by computer simulation. The results show that the proposed method can achieve equivalent BER performance to the conventional one's with much smaller computational cost and no side information. |
