普通GPS接收机在特殊环境下,如在高楼林立的城市中心,林木遮挡的森林公路,特别是在隧道和室内环境的情况下,由于卫星信号非常微弱,载噪比(Carrier Noise Ratio,C/No)通常都在34dB-Hz以下,很难有效捕获到卫星信号,导致无法正常定位。恶劣条件下的定位有广阔的发展和应用前景,特别...
偏移正交相移键控(OQPSK:Offset Quadrature Phase Shift Keying)调制技术是一种恒包络调制技术,具有频谱利用率高、频谱特性好等特点,广泛应用于卫星通信和移动通信领域。 论文以某型侦收设备中OQPSK解调器的全数字化为研究背景,设计并实现了基于FPGA的全数字OQ...
