Abstract
Through fractional sampling, it is possible to separate multi- path components and achieve diversity. However, power consumption grows as the sampling rate increases. In this paper, a novel sampling rate selection scheme in OFDM according to multipath environments is proposed. Numerical results through computer simulation show that the proposed sampling rate selection scheme reduces power consumption by decreasing the sampling rate when delay spread is small.
