Performance analysis of multi-carrier DS-CDMA wireless communication systems
MetadataShow full item record
In this thesis, performance analyses of DS-CDMA, MT-CDMA, MC-CDMA and MC-DS-CDMA transmission systems are carried out in a mobile radio environment .The analysis is conceded out to find the carrier to Multi-Access Interference (MAI) with a Rake receiver. The expression of Bit Error Rate (BER) is found with respect to number of users and SNIR. Also, BER performance results are evaluated numerically. Maximum number of users is estimated at a given BER with a fix number of code length. The required SNIR also find out for that maximum number of users. Results are evaluated in terms of BER with different user codes such as PN sequence, M-sequence, Gold sequence, Hadamard Walsh code sequence for the above schemes.
