| Summary |
A CDMA unslotted ALOHA system using MMSE multi-user detection is proposed.
In CDMA unslotted ALOHA system, a user station can transmit a packet
asynchronously, and so the number of simultaneously transmitted packets
fluctuates moment by moment. This fluctuation affects the performance
of the MMSE multi-user detection.
At first, we employ the Wiener filter detector assuming
perfect information as an upper bound of the performance of the
proposed system.
Then, we apply an adaptive filter to CDMA unslotted ALOHA
to compensate for the birth/death of a packet.
