Abstract

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 paper, a low-complexity SPS scheme is proposed. There is the trade-off between the diversity gain and the estimation accuracy. The serial process of the channel estimation requires only a DFT block with the size of N/4 as the additional circuit.
