Implementation of Morse decoder on the TMS320C6748 DSP development kit

This paper presents a real-time implementation of a Morse code decoder based on the TMS320C6748 digital signal processor. The hardware platform is the TMS320C6748 DSP development kit LCDK. The decoder processes a noisy audio signal, detects Morse signals, selects the strongest one, extracts its dots and dashes, decodes the Morse code and displays the decoded symbols on the VGA monitor in real-time.
