Abstract：

Differential-chaos-shift-keying　(DCSK)　modulation　has　drawn　much　attention　in　the　past　two　decades　due　to　its　simple　realization　and　excellent　anti-multipath　ability.　In　this　paper,　we　conduct　an　in-depth　study　on　the　N-user　DCSK　cooperative　communication　(CC)　systems　over　multipath　Nakagami　fading　channels,　where　three　multiple-Access　(MA)　schemes,　i.e.,　variant-delay　MA　(VDMA),　code-division　MA　(CDMA),　and　Walsh-coded　MA　(WCMA),　are　considered.　To　be　specific,　we　firstly　introduce　the　frameworks　of　the　aforementioned　three　MA-DCSK-CC　systems,　then　analyze　and　compare　the　error　performance　of　these　MA-DCSK-CC　systems.　Analytical　and　simulated　results　illustrate　that　the　WCMA-DCSK-CC　system　enables　more　desirable　error　performance　with　respect　to　the　VDMA　and　CDMA　ones.　Consequently,　the　WC-based　scheme　stands　out　as　a　very　good　candidate　for　the　low-power　and　low-complexity　chaos-based　cooperative　networks.　©　2017　IEEE.
