      CW signal to Morse Symbol decoding block · f8b84707
      Manolis Surligas authored
      The CW symbol decoder block takes as input the power of the processed
      signal and tries to identify the dot and dash symbols. It produces
      asynchronous messages containing the decoded symbols. The output
      messages can be directly used by the Morse code decoder block, in order
      to retrieve the clear text message.
      There are some few thing that need to be done for the block to be fully

      Add a generic clear text message sink. · 5d4884cf
      Manolis Surligas authored
      For now the generic clear text message sink just prints the decoded
      clear text messages in the stdout. In the future and depending the needs
      of the project, the clear text messages can be forwarded at other
      services on the same host or via the network.
      Also the debug message source block now supports injection of artificial
      errors, for more robust decoding of the Morse decoder block.

      Add Morse code debug source block · ebd07215
      Manolis Surligas authored
      Now, with the Morse code debug source block the testing of the decoder
      can begin.
      Add at the examples directory a small flowgraph that connects the debug
      source block with the decoder.

      Morse tree traversal is working · d307d6ac
      Manolis Surligas authored
      Depending the received symbol the tree is traversed towards the leafs.
      At each step the corresponding decode-able character is appended at a
      string buffer. 
      * Add logic in the decoder to retrieve the decoded words from the tree
      * Create a debug source block

      Add morse decoder block. · ca49f817
      Manolis Surligas authored
      The morse decoder is not yet functional. The decoding is performed
      using a binary tree. Left child, corresponds to a received dot whereas
      right to a received dash.
