  Abstract

In this paper, we propose a high level design architecture of WCDMA(UMTS) base station modem and synchroruzation algorithms applied to the proposed architecture Also analysis of each synchronization algorithm and performance evaluation of fixed point designed modem are shown. Since the target system is base station modem, each synchronization algorithm is designed for its stable operation. To minimize implementation complexity, optimum fixed point design for best operation of synchronization algorithms is performed.
We performed symbol level link simulation with fixed point designed modem simulator for data rate of 12.2kbps, 64kbps, 144kbps, and 384kbps. We compared performance results to the minimum requirements specified in 3GPP TS 25 l04(Release 5) Extensive computer simulation shows that the proposed modem architecture has stable operation and outperform the minimum requirement by 2 dB The proposed modem architecture has been applied in the implementation of WCDMA reverse link receiver modem chip successfully.
