【简　介】:Abstract—A method for using sinusoidal transforms as an
alternative to the discrete Fourier transform (DFT) for orthogonal
frequency division multiplexing (OFDM) wireless transmission
methods is presented. These transforms satisfy the cyclic convolution
properties of the DFT when used with a symmetric extension. Analysis of interference in OFDM systems reveals that under certain channel conditions or modulation constellations,throughput is enhanced when using sinusoidal transforms rather than the DFT.
Index Terms—Intercarrier interference, intersymbol interference,
OFDM, sinusoidal transforms.
