This paper considers the joint antenna selection (AS) problem for a classical two-user non-orthogonal multiple access (NOMA) network where both the base station and users are equipped with multiple antennas. Since the exhaustive-search-based optimal AS scheme is computationally prohibitive when the number of antennas is large, two computationally efficient joint AS algorithms, namely max-min-max AS...
In this paper, we investigate the downlink performance of cooperative distributed antenna systems (DAS) in multi-cell environment, including ergodic capacity, outage probability, and bit error rate (BER). Blanket transmission, all distributed antenna modules (DAMs) in one cell are utilized to transmit signals, is considered and can be seemed as virtual multiple-input single-output (V-MISO) system...
Joint decoding at the base stations is investigated as a means to improve the uplink/downlink throughput of current cellular systems over fading channels. In this paper, the multi-cell relay-assisted time-division uplink system, i.e. one active user per time slot per cell with a relay serving that user, is studied. A linear mesh network is considered in which a single user per-cell communicates to...
