    摘要:
    為提高廣義空間調制(generalised spatial modulation,GSM)多輸入多輸出通信系統中頻譜利用率,提出一種混合調制的廣義空間調制(HMGSM)方案。該方案利用激活的發射天線分別調制不同星座符號,其中部分星座符號直接地被調制在激活的天線上;部分星座符號被分成實部和虛部之后,分別調制在激活的天線上。與其他傳統空間調制方案相比,HMGSM方案在相同頻譜利用率情況下具有更大的發射符號之間的最小歐式距離值。在接收端確知信道狀態信息和采用最大似然檢測條件下,通過蒙特卡洛方法對多種技術方案進行MATLAB仿真。結果表明:在相同頻譜利用率時,與其他傳統技術方案相比,HMGSM方案可降低平均誤比特率,進一步提高無線通信可靠性。
    Abstract:
    A GSM with hybrid modulation (HMGSM) was proposed in this paper to improve the spectral efficiency of the generalized space modulation (GSM) scheme.In the HMGSM scheme,the active transmit antennas (TAs) were used to modulate different constellation symbols,some of which were directly modulated on some active TAs and others,divided into real and imaginary parts,were modulated respectively on the other TAs.Compared with the traditional spatial modulation schemes,the HMGSM scheme has larger minimum Euclidean distance (MED) between transmitted symbols at the same spectral efficiency.Under the condition of ideal channel state information and maximum likelihood detection,the MATLAB simulations of various technical schemes are carried out by Monte Carlo method,and the simulation results show that the HMGSM scheme has a lower average bit error ratio (BER) and therefore a higher reliability of wireless communication compared with the traditional schemes at the same spectral efficiency.
