Comparison of Cell Search Methods for Asynchronous Wideband CDMA Cellular System

چکیده
The initial cell search procedure of a terminal in an asynchronous wideband CDMA (WCDMA) system is discussed. The procedure consists of the following steps (not necessarily in this order): chip and frame synchronization; identification and synchronization of the long scrambling code; and determination of the target base station identity. Higuchi et al. [1] proposed a cell search method for such a system. We propose a modification of that scheme which offers substantial terminal complexity reductions with the same performance. The price is a slight increase in delay. Furthermore, we study the impact on performance and complexity for different parameter settings for these methods. key words: cell search, CDMA, chip synchronization, frame synchronization

Bit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...

متن کاملA New and Exact Analysis of DS-CDMA Cellular Radio System Based on the Physical Interpretation of Nakagami Wideband Channel
In this paper we present the performance of two uplink/downlink DS-CDMA receivers in a Nakagami wideband channel. Two detection methods were considered; namely, coherent and differential detection RAKE receivers based on maximal ratio combining technique. We consider a new physical interpretation of the Nakagami channel and the instantaneous power of the multiple access interferers. In comparis...

We evaluate new interference suppression method that utilizes the effect of asynchronous accesses in wireless telecommunication. The method is called as asynchronous channels (ACL), which can be applied to one of the present third generation standards, wideband code division multiple access (W-CDMA) systems. The simulation result shows that the system capacity gains up by 145% in band-unlimited...
