| 抄録: | A new power allocation method for irregularly modulated signaling in single carrier point-to-point multiple input multiple output (MIMO) systems with an iterative frequency-domain (FD) soft cancellation (SC) minimum mean squared error (MMSE) equalization is proposed. The proposed method explicitly takes into account the convergence properties of the iterative equalizer while transmission power is minimized. The proposed scheme is based on the combination of irregular modulation, different signal constellations within one code word, and convergence constraint precoding (CCP), technique that decouples the spatial interference between streams using singular value decomposition (SVD), and minimizes the transmission power while achieving the target mutual information for each stream after iterations at the receiver side. Numerical results show that the proposed scheme improves the transmission rate adaptivity of the original CCP while ensuring the convergence with reduced transmission power. |
