Wireless access in hybrid fiber/coax (HFC) networks can integrate two major telecommunication infrastructure, i.e., wireless and HFC networks. This paper studies the technical feasibility of integrating IS-95 code-division-multiple-access (CDMA) wireless networks and HFC networks. Capacity estimation of an HFC optical node-based CDMA cellular systems using a return-path channel model is provided. In addition to multiple access interference in IS-95 CDMA networks, the returnpath channel model

Furthermore, in our Monte Carlo simulation, we have assumed slow flat fading for radio propagation, and ideal timing recovery and power control.
