Generalized Discrete Fourier Transform (GDFT) with Nonlinear Phase has been forwarded in the literature offering improved correlations and flexible designs over traditional Linear Phase DFT for OFDM communications and many other applications. We maintain this page to provide the interested researchers and technology developers our up to date contributions on GDFT along with other relevant literature.

Although the term "Generalized Discrete Fourier Transform (GDFT)" was used earlier in the literature, the GDFT framework described here is a marked departure from the prior studies due to its use of nonlinear phase basis functions. Moreover, "nonlinear phase orthogonal set" framework is extended to other varieties of Fourier analysis and Laplace transform.

The next generation wireless communications systems employing OFDM based technologies and other DFT applications might benefit from the GDFT framework exploiting the entire phase space.
