Multi-carrier communications based on generalized discrete fourier transform

Generalized Discrete Fourier Transform (GDFT) with non-linear phase is a complex valued, constant modulus orthogonal function set. GDFT can be effectively used in Orthogonal Frequency Division Multiplexing (OFDM) and Code Division Multiple Access (CDMA) communication systems. In this...
