Title: | 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(2/3) | Authors: | 馮世邁 | Keywords: | 多載波調變;單載波調變;multicarrier modulation;single carrier modulation | Issue Date: | 31-Jul-2004 | Publisher: | 臺北市:國立臺灣大學電信工程學研究所 | Abstract: | 這是三年期計畫的第二年。在本計畫 中,我們從理論方面比較 OFDM 系統及 SC-CP 系統的BER 效能。我們證明了在高 SNR 時,SC-CP 系統比OFDM 系統好,在 低SNR 時,OFDM 系統比SC-CP 系統好。 This is the second year of a three-year project. In this project, we analytically compare the BER performance of OFDM systems and single-carrier with cyclic prefix (SC-CP) systems. We prove that for a moderately high SNR corresponding to a useful range of BER, the SC-CP system has a better performance than the OFDM system. For a very low SNR corresponding to a large BER, the OFDM system is better. |
