此篇論文將比較在決定性交錯器條件下之分交錯多工(Interleave-Division Multiple-Access)系統和以金氏碼條件下之分碼多工(Code-Division Multiple-Access)系統作比較,由於IDMA是一種利用決定性交錯器作為關鍵技術來區分不同使用者信號的系統,然而之前提到其交錯器的產生方式為亂數隨機產生,如此將會浪費一部份的頻寬在確認彼此的交錯器,且只有和隨機序列碼之分碼多工做比較。有鑑於此,希望透過一種決定性交錯器加入IDMA的系統,對於每一個使用者只需要傳送一個變數值便能夠決定此使用者的交錯器。模擬結果顯示,使用決定性交錯器之IDMA系統效能同於或優於金氏碼之CDMA系統。
In this thesis, we will provide comparison for deterministic-interleaver-based Interleave Division Multiple Access (IDMA) and Gold-code-based Division Multiple Access (CDMA). IDMA is a system that uses different interleaver to separate different users, but previously the interleaver is generated randomly, which will consume extra bandwidth in informing each others interleaver, and it is only compared to random sequences CDMA. For this reason, by employing a deterministic interleaver into IDMA, interleaver index of each user is determined by only one variable. Simulation results are presented to show that the deterministic-interleaver-based IDMA performance is as good as or better than Gold-code-based CDMA.
