半盲目強制歸零等化器在時空編碼正交分頻多工之應用

The Semi-blind Zero Forcing Equalization in the Space-Time Block Coded Orthogonal Frequency Division Multiplexing Systems

指導教授 : 張豫虎

摘要


本論文中,我們運用時空編碼(space-time block code,STBC)結合正交分頻多工(orthogonal frequency division multiplexing,OFDM)技術,在傳輸通道未知的情況下,運用半盲目強制歸零等化法(zero forcing equalization) ,自動將循環序列(cyclic prefix,CP)去除,並估測出發送端傳送的原始訊號。

In the case of unknown transmission channel, space-time block code combined with orthogonal frequency division multiplexing system is decoded by the semi-blind zero forcing equalization, it can remove the cyclic prefix automatically and estimate the original transmitted symbols.
