How do you reach the full potential of your SFNs?
Posted on March 8, 2014 Leave a Comment
In large SFNs, where the transmitter separation distances exceed the selected guard interval length, self–interference zones might occur within the required service area. These zones might have a very strong negative impact on the network coverage probability. The network planner can apply several different approaches to mitigate the negative effect of the self–interference zones. The […]
A Simplified Description of Coverage Probability Calculations for OFDM Systems in Radio Network Planning Software

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 […]

DVB-T2 is the currently most advanced digital terrestrial television (DTT) system. It is much more flexible, robust, and efficient than any other DTT system. Like its predecessor, DVB-T2 uses OFDM modulation, and offers a wide range of different modes, making it a very flexible standard. DVB-T2 is also offering a very robust signal by using […]
