A CONFIGURABLE MULTI - MODULATION BASEBAND MODULATOR OF SOFTWARE DEFINED RADIO USING FPGA

摘要

The present invention relates to a configurable multi - modulation baseband modulator hereinafter referred as "MMBM" of software defined radio using FPGA. The present invention further relates to a means to extend single digital modulation. Single digital modulation of baseband modulator is extended to multiple digital amplitude and/or phase modulations that can be configured for various applications of software defined radio. The means comprise of modeling a configurable MMBM in digital signal processing basis, generating first hardware description language hereinafter referred as "HDL", designing second HDL, combining the first and second HDLs, synthesizing the combined HDL, implementing the synthesized HDL into FPGA, and measuring the results obtained in real time.
