正交分頻多工系統擁有較高的頻譜使用效率及對抗多重路徑干擾的能力，已廣泛應用於現今及下一代行動通訊的規格中，隨著晶片技術的演進，多顆射頻模組可以整合在單一晶片上，使得多天線系統逐漸普及。考量到對於資料傳輸量的要求以及有限的頻寬限制，採用空間多工的方式在不同傳輸天線上載不同資料進行傳輸，並善用豐富的散射環境藉以提高傳輸率。然而正交分頻多工系統彼此子載波正交的特性一旦發生偏差將會導致子載波之間的干擾與相鄰符元之間的干擾，使得效能表現大幅衰減，因此對於同步電路的效能格外要求。透過多天線系統所接收到的資訊量大於單一天線系統的特性，對於時序同步及頻率同步進行研究。由於以正交分頻多工為基礎的正交分頻多工多重存取技術提供了可調的快速傅立葉轉換大小以維持在不同使用頻寬皆能擁有相同的子載波間隔頻率，對此在時序同步上還必須針對接收信號其未知大小的快速傅立葉轉換點數設計一同步電路。在頻率同步議題上，以數學模型探討不理想效應造成的影響並針對其做補償，且為減少因載波頻率誤差在頻域上對信號帶來載波之間的干擾影響，提出一在時域上的補償方式，以達到系統效能上的要求。本論文根據規格設計一基頻的傳送接收機，利用上述同步技術來實現時序同步以及頻率同步，並將傳送端以硬體實現燒進FPGA內，接收端以SystemC程式執行於PC上，兩者透過PCI介面傳輸來做驗證。
