Parametric Design for Reconfigurable Software-Defined Radio

چکیده
Run-time reconfigurable FPGAs are powerful platforms for realising software-defined radio systems. This paper introduces a parametric approach to designing such systems based on application and device parameters. We analyse the potential for reconfiguration in several software-defined radio components and demonstrate how the degree of parallelism in a reconfigurable module influences reconfiguration time and performance. In a case study with a reconfigurable FIR filter, our method increases the performance by a factor of 2.4.

Software-defined radio (SDR) is the term used for flexible radio systems that can deal with multiple standards. For an efficient implementation, such systems require appropriate reconfigurable architectures. This paper targets the efficient implementation of the most computationally intensive kernels of two significantly different standards, viz. Bluetooth and HiperLAN/2, on the same reconfigur...

Cognitive Radio (CR) and Software Defined Radio (SDR), concepts which were mere proposals to solve the population of services over the past two decades, are now enabled by novel materials and components to offer fully reconfigurable devices. Thus, a convergence of services can be attained within a reduced, or even single RF (Radio Frequency) signal path in the device. A solid design of reconfig...
