Abstract (in Japanese) (See Japanese page) 
(in English) This report proposes a novel reservation-based random access protocol with contention resolution by multiuser detection (MUD). In the proposed protocol, before a user terminal (UT) transmits a data packet (DP), it transmits a small access request packet (AP) composed only of an orthogonal preamble sequence and a UT identifier (UT-ID) in a randomly selected minislot during a short dedicated period. Although some APs may collide, a base station (BS) distinguishes them by the matched filter for the preamble part and then extracts the UT-IDs after separating each AP by means of MUD. For each UT failed to transmit the AP, after BS transmits the assignment information, a small number of minislots are additionally arranged to retransmit it. Thus, by using MUD under the dense condition with the APs, BS can maximally detect the access requests in a short period and this results in a reduction of the overhead. Furthermore, in the assignment of a data slot, BS intentionally assigns multiple UTs in one data slot in order to enhance the efficiency and separates them by MUD when it receives them. Thus, by both the effect of detecting a multitude of access requests by utilizing MUD in the short period and the effect of efficient multiple assignment of separable UTs by MUD, system throughput can be enhanced. Computer simulations are performed and the results show the effectiveness of the proposed protocol.
