Abstract
In this paper, we consider a wireless multi-antenna system using a promising technique, i.e., spatial modulation, and propose an adaptive spatial modulation (ASM) scheme embedded Alamouti space-time block coding (STBC). Instead of selecting one active antenna in each transmission in conventional ASM, we activate two antennas as one antenna group simultaneously to encode the information bits into Alamouti code blocks, each of which needs two channels used. Two detection schemes are presented in different channel conditions, i.e., the maximum likelihood (ML) detection and an adaptive modulation-order selection algorithm. Simulation results show that the proposed scheme improves the error performance and provides larger diversity gain compared to conventional spatial modulation and adaptive spatial modulation.
