Abstract :
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.
