Simple AM Radio Structures on the Spartan3e Starter Kit

The aim of this project was to develop an AM/FM Digital Radio Receiver using Field Programmable Gate Array (FPGA) as the hardware platform. Unlike traditional analog receivers, which are built from analog components, digital receivers convert analog signal into digital representation, and employ digital signal processing techniques to process the digital data for extracting the desired information. The extracted digital information (a radio channel in this case) is then converted back to analog format for listening purposes. In developing the system, we aimed to investigate different techniques for designing digital radio receivers, from which suitable techniques would be chosen for implementing the AM/FM radio receiver. Several design models for implementing the receiver in FPGA would be developed and simulated, giving insight analysis into their performance as well as their efficiency in term of hardware usage. Finally, these models would be translated into software (Hardware Description Language) used for synthesizing the system into a FPGA platform. The ultimate goal of this project will be having a fully working AM/FM Digital Receiver System residing in a FPGA board allowing users to tune in and listen to any of the available AM or FM channels.
