DVB-T2 and Large SFNs – Some Pros and Cons
Posted on September 17, 2013 Leave a Comment
DVB-T2 is today by far, the most advanced digital terrestrial television (DTT) system. It is much more flexible, robust, and efficient than any other DTT system. DVB-T2 uses OFDM modulation, and offers a wide range of different modes, making it a very flexible standard. Due to the multi-path immunity of OFDM, DVB-T2 allows the possibility […]

Orthogonal Frequency Division Multiplexing (OFDM) is a technique that is used in many popular wireless communication systems, such as digital terrestrial broadcast systems (DVB-T, DVB-T2, ISDB-T, DTMB, CMMB, T-DAB, T-DMB), wireless LAN, WiMAX, and LTE. OFDM works very well in radio channels where multipath propagation is particularly noticeable. Multipath propagation generates mainly two effects: intersymbol […]
