    Abstract: 本篇論文探討了在多重輸入多重輸出之正交分頻多工雷達系統中,使用不同序列當作傳送訊號並比較傳送不同序列所得到的錯誤偵測機率。若系統中同時存在多個用戶使用相同頻帶,彼此的收訊會受到干擾,無線通訊存在多路徑傳播亦會形成多路徑干擾,因此無論在同步或非同步的情況下,需要具有理想自相關、互相關函數的序列來克服以上的干擾問題。本文可分為兩部分,第一部分會先介紹五種傳送序列,分別是 m-sequence、gold code、walsh code、Gaussian integer sequence、Zadoff-Chu sequence;第二部分會進行模擬,並將模擬結果與各序列的自相關、互相關函數做比較。;In this thesis, we use different transmitting sequences in MIMO-OFDM radar systems to calculate the probability of miss detection. In wireless communication, both multiple users using the same frequency at the same time and multi-path will cause interference. No matter in synchronous or asynchronous systems, the sequences with ideal auto-correlation and cross-correlation can overcome this problem. Good auto-correlation can separate different paths and good cross-correlation can separate different users. There are two parts in this thesis. In the first part, I will introduce five sequences, such as the m-sequence, gold code, walsh code, Gaussian integer sequence and Zadoff-Chu sequence. In the second part, I will simulate in MATLAB and I will use the correlation properties to explain the simulation result.
