Abstract :
In this paper, we introduce virtual multiple input multiple output (MIMO) techniques into single frequency network (SFN) for providing multimedia multicast/broadcast. Virtual MIMO-based SFN can achieve the full spatial diversity inherent in SFN and greatly improve the reliability of transmission without sacrificing much bandwidth. Furthermore we provide a general method for evaluating the bit error rate (BER) performance of virtual MIMO-based SFN. By this method, we derive an approximate formula for the average BER of M-ary quadrature amplitude modulation (M-QAM). We also present simulations to confirm the formula and compare virtual MIMO- based SFN with traditional SFN.
