DVB-T2 Receiver: Impact of FFT Window Positioning on Radio Coverage
説明
In modern digital terrestrial broadcasting systems, Single Frequency Network (SFN) is a prominent technique used for improved spectrum efficiency, network gain, and increased flexibility. In an SFN, the placement and positioning of FFT window relative to the multiple received signals strongly affect the receiver's behavior of handling Inter-Symbol Interference (ISI). Thus, the treatment of ISI in receiver further impacts on the radio coverage predictions and network planning. In this paper, the radio coverage due to a typical SFN network is evaluated and analyzed for different FFT window synchronization methods. This is repeated for different transmission and reception modes used in the next generation of broadcasting standards and systems specifically in the DVB-T2 system.
