摘要
说明红外光无线通信系统设计的要点，并简略介绍数字信号脉冲位置调制与时段调制比通断键控的优点、角度分集接收和空分多路复用技术。
With an explanation of the design considerations of the infrared optical wireless communication systems,the paper briefly describes the features of pulse position modulation and pulse interval modulation in comparison with on off keying,the angle diversity receiver and space division multiplexing,and the application of infrared optical wireless systems in Local Area Networks.
