PERFORMANCE ANALYSIS OF CODE SHIFT KEYING SPREAD SPECTRUM MULTIPLE ACCESS IN INDOOR,WIRELESS COMMUNICATION

摘要

In this paper,we have considered a Code Shift Keying Spread Spectrum Multiple Access(CSK-SSMA)system for Indoor,Wireless Communication(IWC)environment,which is characterized by a Rayleigh-fading multipath channel.By using Gaussian assumption,we have analyzed interferences from undesired users and multipath fading.We have evaluated the average bit error probability of the CSK-SSMA system in IWC.Our numerical results reveals that the CSK-SSMA system has no advantages over a traditional DS-SSMA system in anti multipath fading and multiuser interference.The results also indicate some form of operation is required to improve the performance of the CSK-SSMA system.
