The authors evaluate new interference suppression method that utilizes the effect of asynchronous accesses in wireless telecommunication. The method is called as asynchronous channels (ACL), which can be applied to one of the present third generation standards, wideband code division multiple access (W-CDMA) systems. The simulation result shows that the system capacity gains up by 145% in band-unlimited rectangular pulse situations. On the other hand, in practical band-limited root raised cosine (RRC) pulse situation, ACL applied system performances are inferior to the conventional synchronous channel systems.
