BER improvement effect of optical delay insertion in ROF ubiquitous antenna architecture for wireless CDMA system

This paper proposes an application of optical delay insertion to a radio-on-fiber ubiquitous antenna architecture for the wireless code-division multiple-access system. The proposed system separates each component of independent signals passing through the multipath in radio and optical links even t...

Description
Summary:This paper proposes an application of optical delay insertion to a radio-on-fiber ubiquitous antenna architecture for the wireless code-division multiple-access system. The proposed system separates each component of independent signals passing through the multipath in radio and optical links even though a mobile terminal exists anywhere in the service area, so the macrodiversity effect is obtained all over the area. As a result, bit error rate performance is improved by setting up the delay time difference between each optical link and the number of taps in the RAKE receiver appropriately.
