Methods and apparatus for providing transparent error correction for wireless Baudot communications

A Baudot-capable error correcting receiver comprising:

• a signal interface for receiving a signal from a transmitter;
• a message extractor for detecting a message containing Baudot information contained in the signal and formatted as a bad frame packet and containing format and content information defining the content of the message;
• and
• a decoder for decoding the message to produce output for a user-operated device.

A method of error-correcting Baudot communication comprising the steps of:

• receiving an input from a user;
• creating a message describing the format and content of the user input;
• formatting the message as a bad Baudot frame;
• and
• transmitting the message.

A method of error-correcting Baudot reception, comprising the steps of:

• receiving a transmission;
• analyzing the transmission to determine if the transmission contains a message formatted as a bad Baudot frame;
• if the message contains a bad Baudot frame, extracting and decoding the message and passing Baudot characters represented by the message to a user device;
• and
• detecting conventionally encoded signals in the message, decoding the signals, and passing the decoded signals to the user device.

An error-correcting Baudot transmitter comprising:

• a user interface for receiving a user input;
• a Baudot decoder operative to examine the input for the presence of Baudot signals and, if the input comprises Baudot signals, to generate Baudot characters representing the Baudot signals, each character containing error data encoded in a stop bit of the character;
• and
• a Baudot encoder for producing a waveform representing the Baudot characters produced by the Baudot decoder.

A Baudot-capable error correcting receiver comprising:

• a signal interface for receiving a signal from a transmitter;
• a Baudot decoder for decoding the signal to form Baudot characters
• a character corrector operative to examine each character to identify error detection and correction information contained in a stop bit of each character and to perform error correction based on the error detection and correction information to produce corrected characters;
• and
• a Baudot encoder for encoding the corrected characters to create a waveform based on the corrected characters.

A method of error-correcting Baudot communication comprising the steps of:

• receiving an input from a user;
• decoding the input to form a stream of error correcting Baudot characters, each of the Baudot characters including error correction and detection information in a stop bit of the Baudot character
• creating a waveform representing the error correcting Baudot characters;
• and
• transmitting the waveform.

A method of error-correcting Baudot reception, comprising the steps of:

• receiving a transmission;
• decoding the transmission to form a stream of Baudot characters;
• analyzing each Baudot character for error correction and information contained in a stop bit of the character;
• if a Baudot character contains error correction and information in the stop bit of the Baudot character, performing error detection and correction based on the error correction and detection information;
• encoding the stream of Baudot characters to create a waveform representing the Baudot characters;
• and
• providing the waveform to a user operated device.
