Design on SCA-based Vehicular Radio System

The use of standard software communication architecture （SCA） can satisfy the balance of flexible performance, reliability, and cost for design of vehicular radio system. This article simply introduces the hardware framework and software framework of the SCA-based vehicle radio system. It mainly discusses control interface of the vehicle PA, heat dissipation of the system and design of the electromagnetic compatibility. The article analyses the co-site interference problem of vehicular radio and proposes suggestions for improvement. It expects that the rapid bus technology, the development of standard SCA technology, etc. could promote the optimization of the vehicular radio system. Finally, the article discusses some primary research directions of the vehicular radio.
