A novel low-complexity iterative receiver in Multiple Input Multiple Output(MNVIO) channel is presented.Partial parallel interference cancellation based on QR decomposition is used in
which different layers is grouped and jointly detected by MAP.The interference between different antennas is cancelled effectively through serially concatenating a soft input soft output(SISO) detector and Turbo decoder by iterative process.Three dimension extrinsic information transfer characteristics(3D EXIT charts) are used to analysis the processes of iterative.Compared with traditional QR based serial interference cancellation iterative rerxiver
tbe performance of the proposed receiver is improved greatly.And it is not sensitivity to the mismatched SNR.
