Develop an FPGA decoder to convert NOAA WAV IQ files into PNG files

Develop and deliver FPGA code in vivado to:

Take in attached NOAA wave file (IQ based) and decode it into a weather satellite image.

This wave file was a recording of from NOAA satellite's Automatic Picture Transmission.

The signal itself is a 256-level amplitude modulated 2400Hz subcarrier, which is then frequency modulated onto the 137 MHz-band RF carrier. Maximum subcarrier modulation is 87% (±5%), and overall RF bandwidth is 34 kHz.

Steps to perform inside FPGA:

1. FM demodulator of IQ data to reveal the AM signal

2. AM demodulator using envelope detector (see [login to view URL] as example)

3. Save binary stream to image file (see reference file attached for expected output)

Skills: Electrical Engineering, Electronics, Matlab and Mathematica, Microcontroller, Verilog / VHDL
