Network Coverage in Multicarrier Broadcast System
Siqian Liu, Hongxiang Li, Benjamin O. Braaten · 2010
In this paper, we discuss the network coverage of the generic multicarrier (or OFDM) based broadcast system by exploiting the frequency diversity over subcarriers. We first define the performance metric and discuss the relationship among broadcast rate, coverage area and the outage probability. To calculate the actual broadcast coverage area, we provide analytical results for both the low SNR and high SNR cases. In addition, we extend our discussion to the multicarrier multicell broadcast network. Simulation results show that multicell cooperation(MCC) has the best performance.
