Abstract
A system and method for transmission of information subject to fading by using a RF carrier modulated with a subcarrier modulated with the information. The system has a processor for providing first and second encoded information streams each comprising the information to be transmitted with the second stream being delayed by a time delay interval with respect to the first stream which is equal to or greater than the fading interval. The first and second information streams are modulated on cycles of the subcarrier to produce first and second parallel information streams. At least one receiver having a detector receives and detects the transmitted first and second parallel information streams. At least one processor determines if faded information is present in the detected first and second parallel information streams. The at least one processor places an error marker within the detected first and second parallel information streams to mark each faded information unit and controls replacement of each error marker within at least one of the first and second parallel information streams with replacement bits within one of the first and second parallel information streams which were time offset at transmission by the time delay interval to produce error free transmitted information.
