This paper addresses the problem of performing orthogonal space-division multiplexing (OSDM) for downlink, point-to-multipoint communications when multiple antennas are utilized at the base station (BS) and (optionally) all mobile stations (MS). Based on a closed-form antenna weight solution for single-user multiple-input multiple-output communications in(More)
With the maturing of fourth generation (4G) standardization and the ongoing worldwide deployment of 4G cellular networks, research activities on 5G communication technologies have emerged in both the academic and industrial communities. Various organizations from different countries and regions have taken initiatives and launched programs aimed at potential(More)
Non-orthogonal multiple access (NOMA) is expected to be a promising multiple access techniques for 5G networks due to its superior spectral efficiency. In this letter, the ergodic capacity maximization problem is first studied for the Rayleigh fading multiple-input multiple-output (MIMO) NOMA systems with statistical channel state information at the(More)
In this paper, we study the uplink performance of an orthogonal frequency division multiplexing (OFDM) wireless system where multiple antennas are utilized at the base station (BS). Further, capacity can be greatly enhanced through spatial division multiple access (SDMA), so that several users can transmit packets simultaneously to the BS. The system(More)
The fourth-generation (4G) mobile communication systems are commercially operated worldwide mainly based on Long Term Evolution (LTE) Release 8. As it evolved, LTE Release 9 was published in 2009 with the introduction of multimedia broadcast multicast services, home eNodeB (eNB), location-based services (LBS), and so on.
