摘要：
This paper proposes a new iterative frequency domain equalization (1-DE) algorithm for multiple-input multiple-output (MIMO)-frequency division multiplexing (G1-DM) systems. This new FDE scheme is capable of enhancing the system fidelity by considering the complete frequency-domain second order description of the received signal. In addition, a new nulling filter design is also proposed for MIMO-GFDM systems to remove the residual interference, which further improves the system fidelity compared with the traditional scheme. Simulation results are presented to verify the effectiveness and efficiency of the proposed 1-DE algorithm.
