## 4 Experimental Analysis and Discussion
The results in Figure 10 are compared among with addressed NLIs and PAPRIs and without addressed NLIs and PAPRIs. Moreover, the results include the individual performance of each addressed NLIs and PAPRIs and without addressed NLIs and PAPRIs, which denotes that in every case, the outcomes without addressing NLIs or PAPRIs are weak and interrupt CN efficiency. The order of NLIs and PAPRIs are increased directly with RF and transmitted length as presented in Figures 11-13. Figure 11 explores the relation among input power and BER for 5 km 6 GHz, Figure 12 presents the outcomes of the presented model based on input power and BER for 10 km 4 GHz and Figure 13 defines the results at 10 km and 6 GHz RF waves, using input power vs BER. In Figure 11 at 0 dBm input power for 5 km length and 4 GHZ RF, \(10^{-7}\) BER is attained, with applying management techniques, minimizing NLIs and PAPRIs. However, about 0.001 less BER is gained using a conventional system if no mechanism is installed for treating the effects of NLIs and PAPRIs. Similarly, \(10^{-6}\) is calculated of the proposed full-duplex RoF model, working at 10 km and 4 GHz RF parameters. Furthermore, Figure 13 estimates \(10^{-5}\) and \(3.1\times 10^{-3}\) BER at 0 dBm, comparing compensation of NLIs and PAPRIs. From Figures 10-13 it is evaluated that outcomes of the full-duplex RoF model are destroyed badly if there are no procedures applied for deducing the NLI and PAPRIs. In addition, it is showed the negative impacts of NLIs are higher than PAPRIs. Figure 14 evaluates the received power vs input power at \(-10\) to 0 dBm for 1, 5, and 10 km fiber length and 6 GHz RF waves. It is depicted from Figure 14 that for higher length because of NLIs, PAPRIs and PEs, the maximum penalty is recorded in received power. The presented model is also investigated, employing BER analyzer, optical spectrum analyzer and RF spectrum analyzer, which are explained in Figures 15a-d, 16a-d and 17a-d. Figure 15a shows the performance of the full-duplex RoF model at 10 km of transmission range and 6 GHz of RF waves. When there is no technique addressed for controlling NLIs and PAPRIs. Figure 15b presents the model without NLIs and PAPRIs compensated at 10 km and 4 GHz RF waves. The compensated NLIs, PAPRIs results of the full-duplex RoF model where NLIs and PAPRIs are reduced depict in Figure 15c,d for 10 km, 4 GHz, and 10 km 6 GHz, respectively. Figure 16a shows the input transmitted signals, Figure 16b,c clarify without NLIs and PAPRIs managed signals at 5 km and 10 km of path cover with RF 4 GHz, respectively. The NLIs and PAPRIs compensated output signals at path cover of 10 km are presented in Figure 16d. Figure 17a contains the results of input signals. Figure 17b consists of interrupted signals due to NLIs and PAPRIs of the proposed full-duplex RoF model at Length = 5 km and RF = 4 GHz. The worst performance at 10 km length and RF 4 GHz of the model without compensated NLIs and PAPRIs is explained in Figure 17c. While outcomes of the applied technique to suppress NLIs, and PAPRIs at 10 km and RF 4 GHz are described in Figure 17d.
