Abstract

To solve the cell-edge problem (deep and flat fading for long time) of multi-cell MBMS in SFN and reduce PAPR in OFDM systems simultaneously, a novel transmission architecture is proposed. Grid scrambling diversity scheme is adopted in the architecture to increase time and frequency diversity. Several grid scramblers are used and the time domain signal with smallest PAPR is selected for transmission. Some simulation results are provided to demonstrate the efficacy of the proposed architecture.
