Exploiting The Dynamic Flexibility Of Software Radio

Abstract- This paper demonstrates how the flexibility of software radio may be exploited to optimise radio communications systems. It describes our implementation of a software radio RDS (Radio Data System) receiver. Most FM stations transmit a RDS signal in addition to their audio output. RDS provides information about the current FM broadcast such as the program name etc. RDS is very similar to the North American RBDS (Radio Broadcast Data System). Our implementation of the receiver uses high level RDS information to adapt itself. The objective is to improve the receiver's functionality for the user and to reduce the computational load.
