摘要：
A simple channel model of wireless optical links based spatial coding is described and two basic channel constraints are outlined. For representing the spatial patterns as signal points, a signal space based 2-D orthonormal basis functions is defined. After that, critical measures of performance are also defined as metrics for comparing candidate modulation schemes. Then three candidate modulation schemes exploiting spatial dimensions are proposed, which are spatial on-off keying, spatial pulse position modulation and spatial quadrature amplitude modulation schemes. At last, the three modulation schemes are compared by power efficiency and bandwidth efficiency. The appropriateness of each scheme is also discussed.
