Abstract
The main purpose of this paper is to assess the performance limits of an analog optical link for 3GPP W-CDMA systems by using a combination of simple two-tone test and analytic simulation results. ACLR of the transmitted IS-95 CDMA and 3GPP W-CDMA signals have been measured and analyzed for multiple frequency assignments (FAs). In 3GPP specifications the required ACLR is ?5 dBc, and the downlink total power dynamic range shall be 18 dB or greater. The required IIP3 and slope efficiency of a DFB laser diode at an optical loss of 10 dB are presented to realize four W-CDMA FAs (20 MHz bandwidth) transmission. Performance limits of a dual-band fiber-optic link to transmit both of IS-95 CDMA and W-CDMA signals are estimated and presented.
