  3. 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(kuò)頻碼的周期的加長會給衛(wèi)星導(dǎo)航定位系統(tǒng)帶來許多相應(yīng)的好處,但問題也就隨著之而來了,擴(kuò)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(tǒng)的并行捕獲方法,將極大的耗費(fèi)硬件資源,而且系統(tǒng)功耗會隨之增大。
