The emergence of portable information terminals in work and living environments is accelerating introduction of wireless digital links and local-area networks(LANs). Transmission using infrared radiation recently become a viable option. As a transmission medium, infrared offers several advantage over radio. The infrared spectral region offers a virtually unlimited bandwidth that is unregulated worldwide. In this paper we examine the performance of several modulation schemes on the wireless infraredcommunication system. We compare the power and bandwidth efficiency of several schemes.
