因此，其中頻數字接收機需要完成偽隨機碼捕獲跟蹤、載波恢復、糾錯譯碼等功能。
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
