Bit Allocation Strategies For Generalised Spatial Modulation

This paper presents an antenna selection and two bit allocation methods for general spatial modulation, all based on channel state information. The proposed antenna selection method maximizes the Euclidean distance between the possible antenna selections in order to decrease the bit error rate. The bit allocation methods aim at determining the neighboring symbols and minimizing the Hamming distance in between them. In some scenarios, we show, through Monte Carlo simulations, that the presented methods have lower computational complexity and perform better than the existing approaches.
