摘要：
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 -45 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.
