摘要：

This paper proposes frequency-encoding code-division multiple-access (FE-CDMA) systems using time-encoding for multiple access interference (MAI) mitigation. Time-encoding is that an incident ultrashort light pulse is split into several pulses with smaller power. In the proposed systems, MAI can be mitigated due to the smaller power and the multiplicity position of those pulses split by time-encoding. We show that the proposed system is effective to reduce the effect of the MAI when the received optical power is large.
