Time frequency localization of pulse shaping filters in OFD/OQAM systems

In this paper we investigate the time frequency localization (TFL) properties of different pulse shapes in OFDM/OQAM systems. Various prototype functions, such as rectangular, half cosine, Isotropic Orthogonal Transfer Algorithm (IOTA) function and Extended Gaussian Functions (EGF) are discussed and implemented in a Matlab/Octave Simulation Workbench for Software Defined Radio by direct discretisation of the continuous time model. Simulation results show that pulse shapes with good TFL properties can have near perfect reconstruction.
