Abstract: Index modulation is a novel modulation technique for OFDM system. In this paper, we propose a novel universal Short Index Modulation filtered (SIMF) OFDM modulation system to overcome the inter-carrier interference (ICI) problem in high-speed environment. In the proposed scheme, the filtering operation is used to reduce the out-of-subblock power leakage to minimize the ICI between the adjacent subblocks. The simulation results indicate that the proposed scheme outperforms the OFDM-IM in the carrier frequency offset (CFO) compression. This paper represents a generalization of Short Index Modulation from orthogonal designs. Particularly, we show in this work, that not only the Alamouti-scheme which was useful only for, SIMF for two transmit antennas, but also its generalized version achieves capacity in the case of one receive antenna. The drafted codes are then analyzed with respect to the bit error rate performance and the spectral efficiency with optimal as well as suboptimal receiver structures. In the second part of this work the combination of Short Index Modulation with conventional channel coding techniques is considered. New SIMF is presented and the performance of Short Index Modulation with iterative algorithms for soft-input-soft-output-decoding is analyzed and optimized with the help of Xilinx Integrated Simulation Environment, the coding part is done in VHDL and the synthesis of work is been develop on Xilinx 12.2. the obtain results are been compared with base works and found better.
