Layered Description and Implementation of CDMA Protocols

  • B. Martin
Conference paper


This paper presents a layered description and the related implementation of CDMA protocols.

Firstly, it shows a protocol stack and a signaling protocol compatible with the IS-95 standard. Since the IS-95 standard doesn’t follow usual layered architecture, it is reconsidered and re-structured. The resulting model includes interfaces for compatibility with UMTS and also broadband systems. It allows integration of packets and high data rate services.

Secondly, the paper describes the Call Admission Controller, for speech, low data rate, high data rate and bursty data services. Particularly, bursty data service introduces the problem of evaluating a traffic model and the time-varying interference.

Finally, a real time demonstrator implementation is described.
