| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | To achieve diversity with a single antenna, a fractional sampling (FS) scheme in OFDM has been investigated. In addition, to obtain more diversity gain through FS, a sampling point selection (SPS) scheme has been proposed. However, it requires a large number of multiplication operations for the SPS. This leads to large power consumption and costs for additional circuits. In this report, a low-complexity SPS scheme is proposed. The proposed scheme decreases the computational complexity by reducing the DFT size for channel estimation. There is a trade-off between complexity reduction and Bit Error Rate (BER) degradation. Moreover, the serial process of the channel estimation requires only a DFT block with the size of N/4 as the additional circuit. |
