  Abstract

Multi-dimensional index modulation is actively studied due to its superior spectral efficiency. This paper proposes an active element selection method and a low-complexity detector applicable to generalized space-frequency index modulation (GSFIM), one of multidimensional index modulation scheme. The proposed active element selection scheme increases data rate by performing spatial index modulation for each submatirx of GSFIM. When the proposed active element selection method is used, the data transmission amount is higher than that of the conventional method, but the same bit error rate performance is shown. The proposed detector reduces the computational complexity of the detector by estimating the index of the active antennas using neural network in the received signal of the GSFIM to which the zero-forcing (ZF) technique is applied. The proposed detector requires lower computational complexity than when only the zero-forcing technique is used, but shows the same bit error rate performance.
