(English Abstract)
Recently, spectral efficiency or reliability is required to be improved in the scenario of multiple access. In this paper, we consider a scenario where two source nodes access one destination node. Different with conventional multiple access studies, in our research, a part of the allocated resource is shared by two source nodes and this scheme is called partial multiplexing. Let Rs denote the ratio of the amount of the shared resource to that of the resource allocated to each user. We analyze and optimize the performance of the partial multiplexing in term of Rsɲɳ. We show that the optimal Rs to maximize the throughput is 1 or 0 based on approximated bit error rate (BER). In addition, if we set a constraint on frame error rate (FER), Rs can have a value between 0 and 1. We also find the approximated Rs to meet the constraint as a closed form. Partial multiplexing can be a novel multiple access scheme.
