Summary:
In the current Long Time Evolution (LTE) broadcast systems i.e. enhanced Multimedia Broadcast Multicast Service (eMBMS) with Single Frequency Network (MBSFN), MBSFN service area edge users may still suffer interference from the adjacent MBSFN or non-MBSFN services which have detrimental effects on the broadcast service spectrum's efficiency as the data rate of a broadcast/multicast system is decided by the receiver with the worst signal to interference plus noise ratio (SINR). In this paper, we consider a scenario independent interference rejection combining a receiver with regularisation to any user with the SINR below a certain threshold, based on a bottom-up concept, that should increase the overall broadcast system spectrum efficiency. The bit error rate results demonstrate that it has a stable performance in both noise-limited and interference-limited scenarios. Space-Frequency Block Coding is used on the transmitter side to increase the transmitter diversity, on top of the existing macro-diversity achieved by MBSFN transmissions. It provides a potential solution for concurrent transmissions of different adjacent MBSFN services at the same time which is currently only supported in a Time Division Multiple Access (TDMA) manner.
