多输入多输出(MIMO)系统在发射端和接收端都由多根天线组成，大大提高了系统的容量。空间调制(SM)是MIMO系统中一种新的传输方式，信号星座点的符号和发射天线在天线阵中的位置传递信息。空间星座点表示发射天线在阵列中的位置。空时分组码空间调制(STBC-SM)结合了空时分组码(STBC)和空时分组码的优点。它利用了多路复用增益和传输分集。另一种传输方案是格子编码空间调制(TCSM)，主要集中在相关信道条件下，其中可用传输天线通过集合划分来分组，使得每个子集中的传输天线之间的距离是最大的。研究了多播MIMO系统中空间调制(SM)、空时分组编码空间调制(STBC-SM)、网格编码空间调制(TCSM)在不同信道条件下的性能。
Multiple-input multiple-output (MIMO) system comprises of more than one antenna at transmitter and receiver which increases the capacity of the system. Spatial modulation (SM) is a new transmission method used in MIMO systems where symbol from signal constellation point and the location of transmit antenna in the antenna array conveys information. Spatial constellation point represents transmit antenna location in the array. Space-time block coded spatial modulation (STBC-SM) takes the advantages of space time block coding (STBC) and SM. It exploits multiplexing gain and transmit diversity. Another transmission scheme trellis coded spatial modulation (TCSM), mainly focused in correlated channel conditions, where available transmit antennas are grouped by set partitioning such that the distance between transmit antennas in each subset is maximum. In this paper, the performance of spatial modulation (SM), space-time block coded spatial modulation (STBC-SM), trellis coded spatial modulation (TCSM) in multicast MIMO system for different channel condition is investigated.
