Windowing and pulse shaping have been proposed to reduce sidelobes in the lit- erature. When these methods are used, addi- tional post-processing equalization is needed at the receiver. The post processing computa- tions are often channel dependent and the co- ecients need to be computed when the chan- nel changes. In this report we consider win- dow designs for the OFDM system. We will design windows that minimize out-of-band en- ergy with the condition that post processing is channel independent.application/pdf136191 bytesapplication/pdfzh-TW國立臺灣大學電信工程學研究所OFDM systemwindowed OFDMout-of-band energyreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/20279/1/912219E002047.pdf
