Abstract
Generalized Spatial modulation (GSM) uses nt antenna elements but fewer radio frequency chains (nrf) at the transmitter. Spatial modulation and spatial multiplexing are special cases of GSM with nrf = 1 and nrf = nt, respectively. In GSM, apart from conveying information bits through nrf modulation symbols, information bits are also conveyed through the indices of the active nrf transmit antennas. In this paper, we derive analytical bounds on the code-word and bit error probabilities of maximum likelihood detection in GSM. The bounds are shown to be tight at medium to high signal-to-noise ratios (SNR). We also present a low-complexity detection algorithm based on reactive tabu search (RTS) for GSM in large-scale MIMO systems. Simulation results show that the proposed algorithm performs well and scales well in complexity.
