| Abstract: | Software design scheme of highly-configurable and high-speed GPS IF digital signal generator was proposed.It is implemented on x86 platform and can simulate satellite signal,propagate channel model and receiving condition such as mixing and sampling.The generated GPS L1 signal can take place of actual sampled signal and provide facilities for the design and verification of navigation receiver.Compared with existing ones,the proposed scheme has features of high configuration,high efficiency and high fidelity. |
