为了有效地利用有限频谱进行机对机(M2M)通信，提出了一种基于空分多址(SDMA)的空分多址(SDMA)通信体系结构，其中考虑了机载自动驾驶系统与地面控制中心之间存在噪声的短消息(SMN)通信的随机接入，以实现空中交通的精确控制，即全4维轨迹管理。仿真结果表明，在信干噪比(SINR)约束下，采用迫零波束形成和低复杂度的飞机分组策略相结合的空分多址机制能够提高频谱利用率。
In order to achieve an efficient usage on a limited spectrum for aeronautical machine-to-machine (M2M) communications, in this paper, a space division multiple access- (SDMA-) based architecture is proposed, where the random access of short messages noisy (SMN) M2M communications is considered between autopilot systems onboard and the ground control center for the air traffic precise control, that is, full 4-dimensional trajectory management. It shows that using a zero-forcing beamforming combined with a low complexity aircraft grouping strategy, the SDMA-based mechanism is able to improve the spectrum efficiency under signal to interference plus noise ratio (SINR) constraints.
