Abstract
Every multicarrier system used in practice has to obey power spectral density limits dictated by standards or other specifications in order to maintain spectral compatibility with coexisting systems. Rectangularly-windowed FFT-based multicarrier systems exhibit significant sidelobes in their transmit spectra. An effective and low-complexity approach to amend this problem is transmit windowing. This paper investigates the most important windowing techniques (intrasymbol windowing, intersymbol windowing, and Nyquist windowing) and casts them into a framework for comparison. A case study illustrates the results.
