Software design of the smart antenna in the connectivity infotainment system

Abstract

This paper designs a smart antenna system for the connective vehicle infotainment. It provides a whole software solution for the Vehicle Head Unit independent with OS system. It includes worldwide analog and digital radio and TV, full radio stacks, FM to DAB on web radio seamlessly, vehicle networking management. This paper is to define the interface between the smart antenna module and the Head Unit. The physical link between the smart antenna and the Head Unit is Ethernet, the interface is based on several protocols based on IP protocol such as UPnP, HTTP to receive a radio signal and use it. Thanks to the open source structures and integrating all the radio stacks, this system is much easier for OEM vehicle companies and Tier one suppliers to adopt the smart antenna into the infotainment Head Unit. It saves them a lot of developing time and cost.
