摘　　要：The iteration-stopping scheme of turbo receiver, consisting of an inner multiple-input multiple-output （MIMO） detector and an outer turbo decoder, was studied in this paper. In the inner MIMO detector, only the reliabilities of bits in those channel slots which included unreliable information bits were updated when the outer turbo code was a systematical one. In conjunction with the trigger events for stopping the turbo decoding, an iteration-stopping scheme of turbo receiver was proposed. Simulation results show that the proposed scheme has lower complexity, but almost the same error performance compared to the scheme with predetermined maximum iterations.The iteration-stopping scheme of turbo receiver,consisting of an inner multiple-input multiple-output(MIMO)detector and an outer turbo decoder,was studied in this paper.In the inner MIMO detector,only the reliabilities of bits in those channel slots which included unreliable information bits were updatedwhen the outer turbo code was a systematical one.In conjunction with the trigger events for stopping theturbo decoding,an iteration-stopping scheme of turbo receiver was proposed.Simulation results show thatthe proposed scheme has lower complexity,but almost the same error performance compared to thescheme with oredetermined maximum iterations.
