Efficient performance of COFDM-based DVB-T

European terrestrial digital video broadcasting (DVB-T) standard has been launched based on the well knows modulation technique; orthogonal frequency division multiplexing (OFDM), which when used in conjunction with channel coding is known as COFDM. This paper will show the efficiency of COFDM in different DVB-T environments based on a compliant DVB-T simulation. An efficiency performance study of COFDM systems-based DVB-T over three different channels has introduced. During this study, there were two different channel coding schemes used with two different coding rates, in addition to the use of two different modulation techniques. Also, using a strong modulation technique, such as 16 QAM, will show better performance than the less power ones, such as the QPSK.
