A　design　scheme　for　shortwave　broadband　OFDM　system　based　on　Raptor　code　is　proposed.　Raptor　code　is　utilized　to　improve　the　channel　capacity　and　erasure　performance,　as　well　as　increasing　the　bit-rate.　In　addition,　OFDM　is　applied　to　increase　the　spectrum　efficiency　of　the　shortwave　broadband　communication　system.　The　experiment　results　demonstrate　that　the　proposed　system　has　the　better　performance　on　error　resilience　and　the　transmitted　bit-rate.
