Abstract :
This paper presents a theoretical analysis for non-coherent multi-tone code division multiple access (MT-CDMA) system in terms of bit error rate (BER). The study considers differential quadrature phase shift keying (DQPSK) demodulation and M-branch post-detection diversity combining for slowly Rayleigh fading and frequency selective channel in the indoor environment. Here, the influence of the order of diversity and number of tones is investigated for given bandwidth (BW), bit rate and transmitter power. The paper also compares the BER performance between differential binary phase shift keying (DBPSK) and DQPSK based non-coherent MT-CDMA systems.
