HF communication system with decoding operations and related methods
First Claim
1. A high frequency (HF) communication system comprising:
- a first HF radio communications device comprising a first HF radio transceiver and a first controller coupled thereto; and
a second HF radio communications device comprising a second HF radio transceiver and a second controller coupled thereto;
said first controller being operable with said first HF radio transceiver and being configured to send a message to said second HF radio communications device, the message comprising;
a preamble portion;
a variable length data portion after the preamble portion and having a given ending point selected from among a plurality of potential ending points with each potential ending point being spaced apart from an adjacent potential ending point by a set quantity of digital data; and
a check portion after the variable length data portion indicating an end of the message;
said second controller being operable with said second HF radio transceiver and being configured toperform a decoding operation on the message at a potential ending point, and perform a check operation on a potential check portion of the decoded message, andwhen the check operation is successful, recover the variable length data portion from the decoded message, otherwise perform another decoding operation on the message at a next potential ending point, and perform another check operation on another potential check portion of the respective decoded message.

Abstract
An HF communication system includes a first device, and a second device. The first device sends a message to the second device, the message including a preamble portion, a variable length data portion after the preamble portion having a given ending point selected from among potential ending points, and a check portion after the variable length data portion indicating an end of the message. The second device performs a decoding operation on the message at a potential ending point, and performs a check operation on a potential check portion of the decoded message, and when the check operation is successful, recovers the variable length data portion from the decoded message. Otherwise, the second device performs another decoding operation on the message at a next potential ending point, and performs another check operation on another potential check portion of the respective decoded message.

24. A method of operating a high frequency (HF) radio communications device communicating with another HF radio communications device, the other HF radio communications device sending a message comprising a preamble portion, a variable length data portion after the preamble portion and having a given ending point selected from among a plurality of potential ending points with each potential ending point being spaced apart from an adjacent potential ending point by a set quantity of digital data, and a check portion after the variable length data portion indicating an end of the message, the method comprising:
operating an HF radio transceiver and a controller in the HF radio communications device to perform a decoding operation on the message at a potential ending point, and perform a check operation on a potential check portion of the decoded message, and when the check operation is successful, recover the variable length data portion from the decoded message, otherwise perform another decoding operation on the message at a next potential ending point, and perform another check operation on another potential check portion of the respective decoded message. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
