The Application of Digital Polynomial-Based Interpolation Filters on Pulse Shaping in OFDM/OQAM Systems

摘要

In this paper it is examined for the first time the utilization of digital polynomial-based interpolation filters as the initial filters in the procedure of projecting pulse shaping filters in OFDM/OQAM (Orthogonal Frequency Division Multiplexing/Offset Quadrature Amplitude Modulation) systems, and the conditions of discrete-time orthogonality are met. The comparison is made with the results of related scientific researches in which good time-frequency localization of pulse shaping filter is achieved and the results are graphically presented.
