— Constant modulus transforms like discrete Fourier transform (DFT), Walsh transform, and Gold codes have been successfully used over several decades in several engineering applications, including discrete multi-tone (DMT), orthogonal frequency division multiplexing (OFDM) and code division multiple access (CDMA) communications systems. In this paper, we(More)
— Recently, a theoretical framework for Generalized DFT (GDFT) with nonlinear phase functions exploiting the phase space to design various constant modulus orthogonal transforms was introduced. This paper extends prior work to design longer bases widely used in real world communications systems. GDFT provides flexibilities in phase space yielding(More)
Recently, Generalized Discrete Fourier Transform (GDFT) has been forwarded as the theoretical framework to design a variety of constant modulus orthogonal complex transforms with non-linear phase. In this paper, we evaluate the auto-and cross-correlation properties of several GDFT solutions and compare them with the popular code families like Gold, Walsh(More)
