Asymptotic Performance of Broadcast Services in IEEE 802.16e with CSTD

The IEEE 802.16e system for multicast and broadcast service (MBS) is further investigated over [4]. It is shown that 802.16e networks can exploit advanced transmission and flexible resource allocation techniques to deliver highperformance MBS delivery within the constraints of the WiMAX Release 1 system profile. A novel per-subcarrier SINR model for single frequency network (SFN) operation is proposed for the scenario in which cyclic shift transmit diversity (CSTD) – a form of delay diversity – is applied at the base station. The utility of CSTD for 802.16e MBS delivery in term of rate and coverage enhancement is investigated in detail based on the exponential effective-SINR mapping (EESM) for frame error rate (FER) prediction. In addition, an asymptotic effective SINR approach is developed for lowcomplexity approximation of the EESM FER mapping, and the proposed approximation is shown to be accurate for MBS simulation, while significantly reducing simulation effort.
