Abstract:
This paper presents the design and implementation of the field-programmable gate array (FPGA) based all-digital frequency modulation (FM) radio receiver with a general-purpose RF front-end. The objective of this paper is to build a FPGA based, fully digitized FM radio receiver including a digital tuning function. This receiver consists of a simple analog RF front-end, an Analog-to-Digital converter (ADC), a FPGA chip and a Digital-to-Analog Converter (DAC). The Virginia Tech software defined UWB board is used as the hardware platform of the radio receiver in this project. This board is built by Dr. Chris Anderson, and equips with an 8-bit 1GSPS ADC and a Virtex2pro70 FPGA. A DAC evaluation board and a radio scanner are used to output the audio. A personal computer (PC) plays the role of the controller to tune the receiving frequency through the RS-232 port.
