2.7.2 Testing of Model for Channel with SNR = 27 dB

The past subsection demonstrates that exhibition of WiMAX framework for the channel with SNR = 20 dB is exceptionally poor. Therefore, the performance of the WiMAX framework is expanded by utilizing a channel with higher channel SNR value. In this area, testing of a model for the channel with SNR = 27 dB is shown and talked about. The graphs for input information and output information appeared in Figs. 2.34, 2.35, and 2.36 have been determined by setting channel SNR = 27 dB. When contrasted with input QAM symbols, the output QAM symbols are scattered in an amount which is truly not as much as that of if there should arise an occurrence of channel SNR equivalent to 20 dB. Additionally, the estimations of BER calculator likewise legitimizes the improvement in BER as out of 526,680 bits, just 2468 bits are getting lost that outcomes in the BER of around 0.0046 as it were.
