The both of the standards are simulated under the effects of Additive White Gaussian Noise (AWGN) Channel and the acquired results are compared according to the Target Bit Error Rate (BER) value which is stated in standards. These results show that DVB-T2 standard outperforms DVB-T standard under AWGN Channel and achieves nearly from four to seven decibels power gain according to code rate and modulation parameters. © 2012 IEEE.Conference Object Kentsel Alanlarda Gölgeleme Etki̇sinin Benzetim ve Anali̇zi̇(Institute of Electrical and Electronics Engineers Inc., 2011) Sancaklı, Sibel; Özen, SerdarA low complexity correlation model for the received signal in shadowing in a mobile radio system was proposed. The predicted autocorrelation function is obtained via a site-specific radio propagation tool which uses ray tracing. L2-norm method is used to fit the proposed model to the experimental results and the model parameters of this method is acquired via numerical optimization. The predicted results are compared with the other models in the literature and we report that our model has lower computational complexity and more suitable for hardware emulator implementations than existing models. © 2011 IEEE.
