  正交分頻多工技術(Orthogonal Frequency-Division Multiplexing, OFDM )為多載波傳輸技術,它擁有更高的頻譜使用效率以及有效地對抗頻率選擇性衰落(Frequency Selective Fading)通道與多重路徑所產生的符元間干擾(Inter-Symbol Interference, ISI)。但OFDM系統的子載波旁瓣會產生很大的旁頻帶(Out-of-Band, OOB)干擾,因此會利用旁瓣抑制技術降低旁頻帶干擾,例如保護頻帶、消除子載波或子載波加權技術等。
  本論文針對OFDM系統旁瓣抑制效能提出量測的方法,使用旁頻帶拒斥(Out-Of-Band Rejection, OBR) 的方式來評估旁瓣抑制技術之抑制干擾的效能。並經由MATLAB/Simulink軟體與軟體定義無線電平台建置量測系統效能,量測並驗證本論文提出之方法可以評估旁頻帶抑制技術的好壞。
  Orthogonal Frequency-Division Multiplexing (OFDM) is a technique of multi-carrier transmission. It has higher spectral efficiency and can also be robust against to the frequency selective fading channels and inter-symbol interference (ISI) caused by multi-path. However, the high sidelobe of the OFDM system will cause out-of-band interference. Therefore, we use sidelobe suppression techniques, such as guard band, cancellation subcarrier and subcarrier weighting techniques, to avoid out-of-band interference.
  In this thesis, we propose a performance measurement for the sidelobe suppression techniques in OFDM system, which uses the out-of-band rejection method to evaluate the performance of sidelobe suppression techniques. Using MATLAB/Simulink software and software-defined radio devices, we verify the measurement scheme which can evaluate the performance of sidelobe suppression techniques.
