N2 - In order to achieve the full potential of massive multiple-input multiple-output (MIMO) systems, joint iterative detection and decoding (JIDD) methods are often used. In addition, minimum mean-square-error parallel interference cancellation (MMSE-PIC) technique is usually employed for JIDD-based MIMO systems due to the good trade-off between complexity and performance. In spite of this, the operations of matrix inversion still bring great pressure to the complexity of the system. In this paper, we propose complexity reduced MMSE-PIC detection methods for JIDD schemes. The presented methods combine the Newton iteration method with MMSE-PIC for JIDD systems to reduce the computational complexity of matrix inversion. The simulation results reveal that the proposed methods can reduce the complexity without obvious performance degradation.
