| 摘 要： | Galileo导航系统信号体制具有多波段性,在各波段上分配的信号带宽很宽,最宽可以达51.150 MHz.为解决宽带信号调制问题,提出了采用TI公司生产的高性能正交混频器TRF370333,使信号从基带直接变到射频.介绍了整个调制方案,实际测试结果表明该方案能够有效、可靠地产生Galileo导航信号.

| Abstract: | The signal scheme of Galileo navigation system has many wave bands and assigning on each wave band of signal bandwidth very breadth.The biggest bandwidth can reach to 51.150 MHz.In order to resolve the problem of modulate the wide band signal,this paper is putting forward to adopt the high performance quadrature modulator TRF370333 made in TI,making the baseband modulate signal change directly to the radio frequency signal.It is introduced in the paper the whole signal modulate scheme.The actual test result... |
