| Abstract | In this paper, a construction method for phase spreading sequences which is suitable for CPM-CDMA systems is proposed. Using these sequences, the performance of asynchronous CPM-CDMA systems with traditional BPSK/OQPSK-CDMA systems and the tradeoff between spreading factor and modulation parameters are considered. Numerical results show that the optimal modulation index for CPFSK-CDMA systems is h = 0.5 and the performance is better for lower values of BbTc in GMSK-CDMA systems. Also, we found that the user capacities of MSK-CDMA systems are 2.3 times larger than that of BPSK/OQPSK-CDMA systems. |
