The digital video broadcasting system is used for high range data transmission and reception through different encoding techniques and encrypted environment using a high bandwidth channel which can transmit higher data rate than the conventional system which works on lower data rates.The proposed system was designed to solve a problem for repetitive change in the used location at high speeds the users can not always be fixed as per the problem. This system is used to reduce the loss in data and also reduce the noise and interference. The Simulation shows that error calculation is less in 16 QA...
The digital video broadcasting system is used for high range data transmission and reception through different encoding techniques and encrypted environment using a high bandwidth channel which can transmit higher data rate than the conventional system which works on lower data rates.The proposed system was designed to solve a problem for repetitive change in the used location at high speeds the users can not always be fixed as per the problem. This system is used to reduce the loss in data and also reduce the noise and interference. The Simulation shows that error calculation is less in 16 QAM over Nakagami (with Filter) channel as compared to other modulation with OFDM. From all the channels and modulations, Nakagami channel achieves better performance with 16 QAM modulations. In the case of 16 QAM, complexity of the system is less. Performance analysis of three multicarrier modulation techniques (OFDM, FBMC and OFDM) has shown that all the schemes are having various advantages and disadvantages. For next generation wireless communication systems, UFMC seems to be most attractive and powerful candidate. It shows advantages of both FBMC and OFDM modulation schemes.
