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

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 process of signal classification and FPGA-based receiver implementation. System efficiency is traded off with implementation time in order to allow fast radio creation. A set of high-level transformations are applied to the unknown signal 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 parameters of the radio are then mapped by means of an Implementation Engine to modules implemented in a general purpose FPGA-based receiver.
