Abstract

In this paper, the performance of a CDMA multimedia packet transmission system is analyzed and simulated in an indoor wireless infrared channel. The indoor wireless infrared channel is modeled as a nondirected diffuse link, and pulse position modulation (PPM) is used as a modulation scheme. From the simulation results, it is shown that the RS coding is very effective in improving the packet-delay characteristics of the CDMA-based packet transmission system. The results of this paper can be applied to design of CDMA-based infrared indoor wireless LAN.
