摘要

本論文以工程角度，針對預編碼正交分頻多工系統(Precoded-OFDM, Orthogonal Frequency Division Multiplexing)家族中抑制ICI (Intercarrier Interference)及提高分集效益(Diversity)等兩類技術先進行分類探討及介紹，並針對OFDM系統中最敏感的參數：峰均功率比 (PAPR, Peak to Average Power Ratio)，加以探討分析其效能；期能為有心之士於Precoded-OFDM應用範疇中提供一個研究參考的機會。

This thesis studies two major issues, Inter-Carrier Interference (ICI) suppression and raising multiplexing diversity, of precoded-OFDM (Orthogonal Frequency Division Multiplexing) system.
We furthermore analyze the performance as well as the influence of Peak to Average Power Ratio (PAPR), which is one of the most sensitive parameter in OFDM system. Various precoding architectures, methods are introduced and compared in this thesis to give some insights to those who is interested in precoded-OFDM system techniques.
