Reconfigurable Automatic Modulation Identification Hardware Module for Software Defined Radio Receivers

562 Abstract— Reconfigurable hardware module for Automatic digital Modulation Identification (AMI) scheme has been developed and presented in this paper. The proposed module has been developed using Matlab/Simulink and implemented on Xilinx Virtex v3200efg1156 FPGA device. The synthesis and test results show that the power required to implement the module is 466 mW and the propagation delay is found to be 70.396 ns. It is also estimated that the utilization of the chip area is 32.11%. The validation results show that the module can be used for identification of modulation schemes used in SDR receivers.
