SM空间调制论文

空间调制英文文献，详细讲解原理Abstract—In this letter, we derive the optimal detector for the so-called spatial modulation (SM) system introduced by Mesleh et al. in [1]. The new detector performs significantly better than the original (~4 dB gain), and we support our results by deriving a closed form expression for the average bit error probability. As well, we show that SM with the optimal detector also achieves performance gains (~1.5−3 dB) over popular multiple antenna systems, making it an excellent candidate for future wireless communication standards. Index Terms—Antenna modulation, spatial modulation, maximum likelihood detection, MIMO.
