Executive Summary

Dense Wavelength-Division Multiplexing (DWDM) technique is a very promising data transmission technology for utilizing the capacity of the fiber. By DWDM, multiple signals (video, audio, data etc) staggered in wavelength domain can be multiplexed and transmitted down the same fiber. The Multiple-Input Multiple-Output (MIMO) wireless technology in combination with Orthogonal Frequency Division Multiplexing (MIMO-OFDM) is an attractive air-interface solution for next-generation Wireless Local Area Networks (WLANs) and fourth generation mobile communication system. This paper provides an overview of the modified integrated DWDM MIMO-OFDM technology and focuses on DWDM transmitter design with adequate dispersion compensation for high data rate of 10Gbps, MIMO-OFDM system design and receiver design.
