Manolis Surligas 1e210087f3 Improved Morse decoding 
The AGC block in the Morse decoding flowgraph is placed now at the
proper position. The output of the matched filter produces now a clear
and distinguishable signal during the presence of a pulse. This makes
the work for the signal to symbol decoder more easy.

Examples

This directory contains a set of useful examples and flowgraphs for testing and demonstrating the performance of the different components of this OOT module

Files

  • morse_ref.wav : This is a reference file containing the HELLO WORLD message. The file is sampled at 8 KHz and the audio frequency is 700 Hz. The Morse code Words per Minute (WPM) is about 20.

Flowgraphs

  • test_matched_filter.grc: Demonstrates the performance of the implemented matched filter for CW decoding.
