AUTOMATIC ERROR CONTROL SCHEME SELECTION FOR FIXED-LENGTH MESSAGES BASED UPON MESSAGE PAYLOAD SIZE

摘要

A communication system enabling wireless transmission of messages via packets; and a method of operating the system provides for improved accuracy in the transmission of a message, particularly for overcoming signal distortion associated with the phase changes and varying multipath found in transmissions from the locomotive of a moving train. The maximum benefit of forward-error correction (FEC) with Reed--Solomon (RS) coding is applied for a message payload that is significantly shorter than the fixed length of a packet, with lesser coding being performed with longer payloads.
