⎯This paper presents the theoretical analysis for Noncoherent multi-tone code division multiple access (MT-CDMA) system in terms of average bit error rate (BER). The system uses differential binary phase shift keying (DBPSK) modulation and post-detection diversity combining, considering slowly Rician fading and frequency selective channel in the indoor environment. Post-detection diversity is considered because it non-coherently combines the received signals from different diversity branches after differential detection. Here, the influence of the order of diversity and number of tones is studied for given bandwidth (BW), bit rate and transmitter power.
