摘要：
In indoor optical channels. intersymbol interference (ISI) due to multipath propagation prevents high data rate transmission. In this paper, a new Optical Multi-Wavelength Modulation technique has been investigated for improving the quality of transmission. In this technique, parallel transmission is used, which lowers the data rate per channel and thus reduces the effects of ISI. Furthermore, parallel coding is used in predetermined parallel branches, so that coding can correct errors without changing the system data rate. Simulation results show that a combination of these methods can achieve high quality transmission without reduction of the total data rate.
