Title
Multi-User Successive-Coded Spatial Modulation Scheme Based on Beamforming
Abstract
By combining an existing successive-coded spatial shift keying (SC-SSK) modulation scheme with a modulation scheme that uses the traditional constellation, we propose a new successive coded spatial modulation (SC-SM) scheme. This scheme uses spatial domain and constellation domain to jointly transmit information bits, which increases the achievable rate of the system. In order to extend the SC-SM scheme to multi-user scenario, a multi-user SC-SM (MU-SC-SM) scheme based on beamforming is proposed. The proposed MU-SC-SM scheme not only eliminates the inter-user interference (IUI) and enhances the received signal-to-noise ratio (SNR) of the served user, but also resolves the conflict between beamforming and spatial modulation. The achievable rate, the bit-error-rate (BER) performance and computational complexity of the proposed MU-SC-SM scheme are analyzed in detail. The impacts of the imperfect channel state information on the BER performance are also analyzed. Simulations are carried out to verify that the proposed MU-SC-SM scheme is superior to existing multi-user spatial modulation schemes in BER performance.
