This paper proposes a new full non-orthogonal integration scheme for unicast and broadcast data streams in future OFDM system, in which broadcast is deployed in single cell scenario. It is firstly analyzed why today's research results of the integration of unicast and broadcast in Single Frequency Network (SFN) manner cannot work in single cell deployment scenario. By adjusting the modulation constellation...
In LTE E-MBMS, the fundamental technique is single frequency network (SFN), which simplifies the design of receiver. Under the architecture of SFN, the spectral efficiency is constrained by the maximum transmission power of the base station. According to the evaluation results of LTE E-MBMS, the maximum achievable spectral efficiency is around 1bit/s/Hz, however which can not meet the LTE-A requirement...
