Detecting or Correcting One or More Errors in Data

A method for a receiver apparatus to detect or correct one or more errors in received data, the method comprising:

• receiving data via a channel, wherein:
• the data comprises one or more symbols;
• each symbol corresponds to one of the following states:
• a ground state, and one or more energized states;
• at least one of the symbols corresponds to the ground state;
• and
• the only possible transitions in the channel are the one or more energized states transitioning to the ground state;
• and
• analyzing the one or more symbols to determine whether a transition of one or more of the corresponding states has occurred;
• and
• when it is determined that a transition of one or more of the states has occurred, detecting or correcting one or more errors in the data.

A method of transmitting data in a channel, the method comprising:

• forming data for transmission, wherein:
• the data comprises one or more symbols;
• each symbol corresponds to one of the following states:
• a ground state, and one or more energized states;
• at least one of the symbols corresponds to the ground state;
• and
• the only possible transitions in the channel are the one or more energized states transitioning to the ground state;
• and
• transmitting the data in the channel.

A receiver apparatus configured to detect and correct errors in received data, the apparatus comprising:

• a processor;
• and
• a memory operably coupled to the processor and containing executable instructions, wherein execution of the instructions by the processor causes the apparatus to:
• receive data via a channel, wherein:
• the data comprises one or more symbols;
• each symbol corresponds to one of the following states:
• a ground state, and one or more energized states;
• at least one of the symbols corresponds to the ground state;
• and
• the only possible transitions in the channel are the one or more energized states transitioning to the ground state;
• and
• analyze the one or more symbols to determine whether a transition of one or more of the corresponding states has occurred;
• and
• when it is determined that a transition of one or more of the states has occurred, detect or correct one or more errors in the data.
