Abstract

Nonorthogonal code shift keying code division multiple access (CSK/CDMA) ALOHA is expected to improve the throughput in advanced wireless network, such as sensor networks and ad-hoc networks. The throughput of the nonorthogonal CSK/CDMA ALOHA is expected to get better by introducing the interference cancellation technique. It is not clear how much the throughput improved by introducing the interference canceler. This paper presents the throughput performance of the nonorthogonal CSK/CDMA ALOHA with the interference canceler by theoretical analysis. Consequently, it is found that the throughput performance of our system is over 1.0.
