標題: | 智慧型音視訊和傳輸技術及多媒體應用─子計畫四:應用於多媒體傳輸之先進多載波調變技術(1/3) | 作者: | 馮世邁 | 關鍵字: | OFDM system;windowed OFDM;out-of-band energy | 公開日期: | 2003 | 出版社: | 臺北市:國立臺灣大學電信工程學研究所 | 摘要: | The transmitter output of the OFDM sys- tem is known to have large spectral side- lobes. 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. |
