Rapid radio: A framework for human-assisted signal classification and receiver implementation

Abstract

An analysis-based framework for the rapid development of a radio receiver for signals with unknown parameters is pro-posed, exploiting the reconfiguration capabilities of FPGAs. The framework guides a non-expert user through the proc-ess of signal classification and FPGA-based receiver im-plementation. System efficiency is traded off with imple-mentation time in order to allow fast radio creation. A set of high-level transformations are applied to the unknown sig-nal based on different hypothesis about the modulation scheme. The results of the transformations are presented to the user, who can steer the process of analysis. The parame-ters of the radio are then mapped by means of an Implemen-tation Engine to modules implemented in a general purpose FPGA-based receiver.

On the Implementation of a Quasi-Generic Synchronization Architecture for Linear Digital Modulations

“…The uncertainty about the modulation scheme of signals has resulted in the creation of signal classification systems that attempt to determine the modulation scheme used by the received signal [4][5][6][7]. One such system is the RapidRadio framework [8], which seeks to automate both the process of modulation classification and receiver deployment. A key concept of RapidRadio is that a rapidly deployed receiver should work for any linear modulation scheme, not just the ones envisioned at design time.…”
