Keywords:
Enhancing, Television, Signal, Quality, Advanced, Modulation, TechniqueAbstract
The poor broadcasting and telecommunications qualities in our television broadcasting stations were as a result of low bandwidth, high bit error rate and low signal to noise ratio. This poor broadcasting and communication qualities observed in our television stations was overcame by introducing enhancing television signal quality using advanced modulation technique. To vividly achieve this, it was done in this manner, television signal quality was characterized and the causes of poor television signal quality was established. Then a conventional SIMULINK model for television signal quality was designed and Artificial Neural Network (ANN) was trained in the designed advanced modulation rule base to boost the minimization of the causes of poor television signal quality. The algorithm to implement the process was developed, SIMULINK model for Enhancing Television Signal Quality Using Advanced Modulation Techniques was designed and the results obtained were validated and justified. The results obtained were the conventional Bandwidth Efficiency that causes poor television signal quality was 2 bps/Hz. On the other hand, when an Advanced Modulation was integrated into the system, it simultaneously improved to 2.6 bps/Hz, thereby enhancing bandwidth efficiency to 3.3% and the conventional bit error rate that causes poor television signal quality was 0.001bits.meanwhile, when Advanced Modulation was imbibed into the system; it instantly reduced it to 0.000867bits. Finally, with these results obtained, it showed that percentage enhancement in Television Signal Quality was 13.3%.
