FPGA BASED SDR FOR DPLL APPLICATION

To design and develop a system on chip reconfigurable modules Field Programmable Gate Array (FPGA) provides a way with high performance. In this paper, FPGA architecture is proposed, which would be a starting point for developing an efficient Software Defined Radio (SDR) architecture for recovering audio signals from digitally modulated frequency wave. At the modulator and demodulator sections, a Digital Frequency Generator (DFG) is applied for generating the carrier wave by exploiting the quarter wave symmetry of sine or cosine waves with dynamic range of more than 90dB.
