Traditional multiuser detector make good use of all signals which resuilt in multiple access interference so that it provides optimum mai resistance. ( 1 ) nevertheless, it assumes that the receiver can acquire the signature waveform and timing of desired user and the interfering users ; ( 2 ) it has no ability to suppress intercell multiple access interference ; ( 3 ) it cannot be applied in downlink channels. adaptive multiuser detector eliminates the need to know the signature waveforms and the timing of the interferes and has to need training data sequences for every active user
傳統多用戶檢測在單用戶檢測技術基礎上，充分利用造成多址干擾的所有用戶的信息進行聯合檢測，從而具有良好的抗多址干擾能力，但存在一些缺陷： （ 1 ）不僅要求知道期望用戶的地址pn碼及其定時信息，還要求其他干擾用戶的地址pn碼及其定時信息； （ 2 ）不能消除其他相鄰小區的多址干擾對本小區的影響； （ 3 ）不能直接應用在cdma移動通信系統中的下行鏈路。The actual use and theory analysis indicate that labwindows / cvi development kit can enhance perfectly system real time measurement and control abilities ; detailed data formats can be transformed easily target database by mfc odbc ; real _ time main memory database directly accessing main memory is a perfect scheme to meet the real time requirement ; priority levels and data view that are designed on system characteristics, can solve primely the problem of time sequence consistency ; ntp can basically meet system time synchronization requirement
理論分析和編程實現結果表明labwindows cvi作為測試控制軟體開發工具對系統實時測試、控制性能有很大的提高； mfcodbc能極其方便地實現對具體的數據格式進行數據轉換；以內存直接尋址方式的實時內存數據庫是解決系統實時性的理想方案；針對系統特點而設計的優先級和數據視圖能很好的解決系統時序一致性問題； ntp協議軟體同步演算法基本滿足系統同步精度要求。
