"In defence communication systems, spread-spectrum techniques such as frequency-hopping (FH) have been utilized to provide some protection against jamming. However, an intelligent jammer can drastically reduce the effectiveness of such a system. This effectiveness can be regained through the use of error correcting codes. In this report we present the results of a comprehensive study of the performance of various error correcting codes when used in a frequency-hopping system"--Introduction, page 2.
