Abstract:

This report describes the results of an investigation of the combined design of an asynchronous-to-synchronous multiplexer and error correction coding techniques for megabit data transmission over a troposcatter channel. In addition to the conventional interleaved coding approach, adaptive feed forward coding techniques, such as multiple rate and block interleaved product codes, were studied.
