This design is based on WSSUS channel model. We achieved a real-time signal processing channel emulator which used the channel parameters provided by the DRM criteria. The article first introduces the WSSUS channel model, and then bases DRM criteria to determine the model parameters. Finally, through a structured design, we realized the model HF channel emulator by C language programming.
This paper first reviews the polyphase filter in the decimation and interpolation application, and simply introduces the multi-rate system. And then through the simulation experiments, the characteristics of the sub-filter of the polyphase filter were analyzed. Finally, according to the characteristics of the sub-filter, this paper presents an application in multipath delay.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
