The Digital Terrestrial Television is oriented to replace the transmissions of analogical television, when using the OFDM modulation (multiplexing by orthogonal division of frequencies), with this modulation it is possible to carry out transmissions for fixed and mobile equipment. However, in the case of digital television reception systems such as smartphones, laptops and other mobile devices have reception problems caused by the multipath effect. This project simulates OFDM and CC-OFDM (Orthogonal Frequency Division Multiplexing by Convolution Coding) modulations for the ISDB-T (Integrated Services Digital Broadcasting for Television) television standard. Using Simulink from the Matlab environment, the block diagrams of both architectures were simulated to observe the results when transmitting data, measuring the BER (Bit Rate Erron), the delay and the number of carriers, under the following channels: AWGN (Additive White Gaussian Noise), Land type A (rural terrain) and Land type C (urban terrain). The results obtained show that the CC-OFDM modulation has a higher efficiency, due to the fact that it presents a higher BER and a reduction in the delay in reception.
