In this paper, performance analysis of multi-tone (MT-CDMA) transmission system is 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 signal to noise and interference (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 is also found out for that maximum number of users. Results are evaluated in terms of BER with different user codes such as PN sequence, M-sequence, and Gold sequence for the above scheme.
