Paper Review: Implementation of Morse Decoder TMS320C6748 DSP Development Kit

Morse Code has been used for communication right since the Second World War. Then, the radio operators used to decode the received morse signal by hand. But today, we have technology to make our life easier. What if we used processors to decode the incoming morse signal?

This paper did exactly that. The authors used a Digital Signal Processor to implement a real time morse decoding system. They used a noisy audio signal as in input, filtered the signal digitally and extracted the dots and dashes that make up the morse code. Thanks to the DSP algorithm, all of this could be done in real-time. An added advantage was, it used several basic DSP algorithms like the Cooley and Tukey FFT algorithm, making the setup useful for teaching purposes.
