Paper Abstract
The performance of high-speed non-directed diffuse indoor infrared wireless communication is mainly affected by intersymbol interference (ISI) due to multipath dispersion. The direct-sequence spread spectrum systems are applied to combat multipath dispersion. However, when the data rate is close to the channel 3dB bandwith, the spread spectrum technique may have a worse performance than OOK transmission as it is affected by more severe ISI. Exploiting muli-spot link, we can improve the performance of spread spectrum technique to be much better than OOK modulation because a higher channel bandwith are obtained. Both the analytical and simulation results are presented.
