This article describes a graphical approach for multi-standards SDR design formalization. An SDR consists of software components whose behavior can be changed by reconfiguration procedure. In a common operator design this change requires only an adjustment of certain parameters. The optimal way of realizing a multi-standards terminal is to identify the common functions and operators between standards...
In the Software Defined Radio (SDR) area, parameterization is becoming a very important topic in the design of multi-standard terminals. In this context, the Common Operator (CO) technique defines an open and optimized terminal based on a limited set of generic components called Common Operators. The method was already described in and a new relevant possible CO was presented: R-LFSR based CORDIC...
In the context of Software Defined Radio (SDR), parameterization technique is an interesting approach for the design of multi-standard terminals. It limits the size of the software to a small set of parameters thereby decreasing the radio reconfiguration time. In the proposed research, we refine the Common Operator (CO) technique, which defines a multi standard terminal, based on a limited set of...
This paper proposes a functional management architecture for cognitive radio systems. It relies on a previously defined configuration management architecture for multi-standard SDR systems, and complement it to support cognitive radio features. This paper explains the requirements of cognitive radio systems in terms of reconfiguration, smartness and sensing capabilities. A configuration management...
