Troposcatter Interleaver Study Report.
Abstract
The report represents a detailed investigation of the application of error-correcting coding techniques for troposcatter communications. The importance of time domain coding techniques, which require a certain amount of decoding delay, is demonstrated. Minimization of this required decoding delay is achieved by certain new adaptive coding techniques which require less decoding delay than the more conventional interleaved coding approaches. For tactical troposcatter links operating with single or dual diversity links, it is anticipated that a coding gain (reduction in the required transmitter power to achieve an error rate below 0.00001 in the order of 10 dB should be typical with decoding delays as short as 1/4 second. This savings in transmitted power strongly suggests that single or dual diversity tactical troposcatter links, which use efficient error-correction coding concepts, are not only feasible but also represent an attractive and cost-effective alternative to the more conventional quad diversity configurations.
