One mechanism to support anti-jam on a commercial product as opposed to relying solely on purpose-built frequency hop spread spectrum systems is to couple the coding gains of direct sequence spread spectrum (DSSS) with the channel-hopping capabilities native to a time division multiple access (TDMA) very small aperture terminal (VSAT) system.

In research and testing of anti-jam technologies, I have been impressed with the potential of signal excision for highly sensitive defense, homeland security, government and first responder communications use.
