A New 5G Cellular Broadcasting Approach: Hybrid LDM-NOMA and FeMBMS-OMA Analysis Based on Stochastic Geometry

Abstract

In this paper, an alternative hybrid infrastructure to complete the media cellular TV puzzle called 5G broadcast is introduced and developed. The performance of a non-orthogonal and orthogonal physical hybrid layer for cellular broadcasting is investigated. A downlink layered division multiplexing with non-orthogonal multiple access (LDM-NOMA) together with a further evolved multimedia broadcast multicast service with orthogonal multiple access (FeMBMS-OMA) is superimposed. In our scenario, we have defined them as two broadcast service providers (BSPs), whereby the former recruits the latter as a cooperative layer. Service selection is done by using a binary factor access technology. We assume that there is perfect knowledge with channel state information for Rayleigh fading multipath channel. Bit error rate (BER) and outage/coverage capacity are selected as our inquiries stochastic geometry benchmarks. The spectrum constellations of the scheme are worked according to the resource block (RB) element/symbols and different modulations. The proposed framework can work without a subscriber identity module (SIM card) uplink and internet protocol (IP). Mathematical analysis, based on the exact closed-form expressions, is consistent with the theory of the proposed LDM-NOMA and FeMBMS-OMA. The simulation results are based on the Monte Carlo iterative methodology, and demonstrate the superiority of the hybrid framework compared to each of the technologies separately.
