普通GPS接收機在特殊環境下,如在高樓林立的城市中心,林木遮擋的森林公路,特別是在隧道和室內環境的情況下,由于衛星信號非常微弱,載噪比(Carrier Noise Ratio,C/No)通常都在34dB-Hz以下,很難有效捕獲到衛星信號,導致無法正常定位。惡劣條件下的定位有廣闊的發展和應用前景,特別...
偏移正交相移鍵控(OQPSK:Offset Quadrature Phase Shift Keying)調制技術是一種恒包絡調制技術,具有頻譜利用率高、頻譜特性好等特點,廣泛應用于衛星通信和移動通信領域。 論文以某型偵收設備中OQPSK解調器的全數字化為研究背景,設計并實現了基于FPGA的全數字OQ...
