Nowadays, many embedded sensors allowing localization and communication are being developed to improve reliability, security and define new exploitation modes in intelligent guided transports. This paper presents the architecture of a new system allowing multiuser access and combining the two main functionalities: localization and high data flow communication. This system is based on cooperative coded radar using a transponder inside targets (trains, metro, etc). The sensor uses an adapted digital correlation receiver in order to detect the position, compute the distance towards the preceding vehicle, and get its status and identification. To allow multiuser access and to combine the two main functionalities, an original multiplexing method inspired from direct sequence-code division multiple access (DS-CDMA) technique and called sequential spreading spectrum technique (SSS2) is introduced. This study is focused on presenting the implementation of the computing unit according to limited resources in embedded applications. Finally, the measurement results for railway environment will be presented.
