Abstract：

In　order　to　enhance　the　anti-jamming　capability　of　cyberspace　data-link　in　the　complex　electromagnetic　environment,　a　simultaneous　transmit　and　receive　cognitive　anti-jamming　(SCAJ)　strategy　based　on　transmit-sense-receive　mode　is　proposed　in　this　paper.　Real　time　anti-jamming　can　be　achieved　by　dynamically　allocating　the　sensing　timeslot　and　receiving　timeslot.　We　study　the　jamming　sensing　performance　of　the　proposed　SCAJ　scheme　based　on　energy　detection.　The　closed　expression　of　jamming　detection　probability　under　fading　channels　is　derived,　and　the　system　capacity　of　SCAJ　is　analyzed.　Simulation　results　show　that　the　proposed　SCAJ　technology　can　enhance　the　jamming　sensing　capability　of　cyberspace　data-link　and　improve　the　system　capacity　in　the　region　with　low　self-interference.　©　2016,　Press　of　Chinese　Journal　of　Aeronautics.　All　right　reserved.
