Then three candidate modulation schemes exploiting spatial dimensions are proposed. At last, the three modulation schemes are compared by power efficiency and bandwidth efficiency. It shows that spatial quadrature amplitude modulation scheme is appropriate for long distance wireless optical communications for its high bandwidth efficiency and spatial circular symmetry.

参照传统时域信号设计方案，提出了三种空间调制信号具体设计方案，并从带宽效率和功率效率两性能上进行了比较，结果表明正交幅度调制具有带宽效率高、功率效率低的特点，而且采用的信号点越多其带宽效率就越高，另外其空间信号图案还具有圆对称性，因此非常适合在空间带宽有限的远距离无线光通信中使用。
