Abstract :
The bit error rate (BER) performance of a noncoherent MT-CDMA system is evaluated for a multipath, slow fading Rician and frequency selective channel in the indoor environment. Considering a Gaussian assumption for the whole decision variable, an existing mathematical model is used for computation of the bit error probability using differential binary phase shift keying (DBPSK) modulation. The influence of different combinations of number of tones and code lengths is studied with multiple access interference (MAI)
