This paper proposes coordinated beamforming (CB) that works over non-orthogonal multiple access (NOMA) scheme integrated with spatial modulation (SM), termed as CB NOMA-SM, to improve capacity and user fairness. User capacity, ergodic sum capacity (ESC), and user fairness of K number of coordinated base stations (BSs) are simulated and analyzed by comparing them with joint transmission coordinated multi-point based NOMA with SM (JT-CoMP NOMA-SM), NOMA, and orthogonal multiple access (OMA). The results show that the proposed system outperforms the other schemes both in ESC and user fairness due to the enhancing CEU while CCU capacity still can be maintained. INDEX TERMS Non-orthogonal multiple access (NOMA), coordinated beamforming (CB), spatial modulation (SM), capacity, user fairness.

By the taking account the effect of MobileBroadband on the socio-economic aspect, therefore LTE implementation in Digital Dividend spectrum provides most ideal solution to accelerate the availability of affordable and universal broadband access to whole society in order to fulfill the coverage and capacity target of Indonesia National Broadband Plan. However, the utilization of Digital Dividend spectrum for Mobile Broadband is only be realized after complete Digital Switchover process because the very slow progress of migration of Analog TV to Digital TV and the reluctance of Broadcasters to proceed the migration. In this research, the techno-economy model to accelerate the Digital Switchover process is developed by involving the potential of Digital Dividend LTE Spectrum Fees and providing incentives to reduce necessary cost of Broadcasters in Digital Switchover process such as set-top-box incentive, Digital TV leasing capacity operational expenditure and capital expenditure of Multipex Digital TV in Indonesia. The contributions of this research are to analyze the scenarios that feasible to accelerate the migration of Analog TV to Digital TV and the most sensitive variable concerns the acceleration model of Digital Dividend implementation which developed.
