Abstract：In this paper,KM sequence is presented as a potentially spreading code for CDMA (Code division multiple access) system with RAKE receiver.First,based on a RAKE receiver modeling,the performance of CDMA system with RAKE receiver is analyzed,and the properties of PN sequences that are suited to the CDMA system with RAKE receiver are showed.Next,the advantages and disadvantages of KM sequences as spreading codes for CDMA system with RAKE receiver are analyzed systematically.Finally,the cross-correlation functions between m sequence and KM sequence,and the average bit error probability (BEP) corresponding to both the sequences and Gold sequence under correlating receiver and RAKE receiver,are compared.The feasibility of KM sequence as spreading codes for CDMA system with RAKE receiver is verified.
