This paper investigates the key technology of the ds - cdma system - psendonoise ( pn ) code acquisition technology . various pn code acquisition scheme has been introduced here
本文對ds - cdma系統中的關鍵技術?擴頻序列的捕獲?進行了深入的研究，介紹了擴頻序列的多種捕獲方案。
However , the longer length of c / a code , the more hardware resource and power it cost . this dissertation commits research on algorithm of c / a code acquisition in satellite navigation position system , and compares the acquisition means of digital differential matched filter ( ddmf ) with traditional means , and also achieves ddmf with the vhdl language and fpga platform
擴頻碼的周期的加長會給衛星導航定位系統帶來許多相應的好處,但問題也就隨著之而來了,擴頻碼的周期越長,同步捕獲所需得的時間就越長,而且若用傳統的并行捕獲方法,將極大的耗費硬件資源,而且系統功耗會隨之增大。
At last the algorithm of ddmf is achieved by the investigation tool of altera company ? quartus ii and the vhdl language , and its ip core is also achieved which is used not only in the satellite navigation position system , but also in the long pn code dsss system . ddmf investigated in the dissertation gives a good way to design the rapid pn code acquisition in the beidou project , and the technology has the definite theory and practice significance
此外還應用altera公司的最新的fpga開發工具quartusiiv5 . 1 ,采用了國際標準的硬件描述語言? vhdl語言,對數字差動匹配濾波器和傳統匹配濾波器算法予以實現,開發了該算法的軟ip核,可以對所應用的擴頻碼長度, a / d采樣后的數據量化階數,所用擴頻碼等可進行隨意改寫。
Because the hybrid acquisition scheme ( combines parallel search with serial search ) based on the correlator provides the flexibility in the trade - off between the mean acquisition time and system complexity and is easy to implement , it ? focus on the scheme here . on the other hand , this paper analyzes the effect of multiple access inference ( mai ) on the code acquisition performance for the multipath fading channels
