Convergence of Wireless and Optical Networks for 5g

Project Details


General objective Reduce the PAPR in multiporator systems for 5G through clipping techniques to reduce the effect of fiber optic nonlinearities in converged networks. Justification Currently, the large number of applications of big data analysis, artificial intelligence, the Internet of Things, augmented reality and online video games have increased research on systems that allow high capacity, low latency and can be connected anywhere and anywhere. at any time. Due to the above, wireless networks for 5G must change their modulation technique to a new one that allows reducing bandwidth and allowing more services to be included in the same bandwidth, at the same time it must consider reaching great distances since reduced costs. However, reaching great distances is subject to using transmission media with low attenuation such as fiber optics, although these have non-linearities that are more evident with increasing power and reduce system performance. In the same way, the set of optical and radio frequency (RF) devices for connectorization and amplification of nonlinear characteristics affect the transmitted signals, increasing the loss of information. On the other hand, the signals proposed for wireless networks for 5G suffer from power peaks known as PAPR (Peak to Average Power Ratio) that increase the non-linearities of the optical fiber and saturate the RF amplifiers, the techniques to reduce the PAPR used in signals in 3G and 4G wireless networks that use OFDM are not suitable for these new waveforms. Consequently, research on techniques that reduce the PAPR in the new waveforms and at the same time allow their easy implementation in converged real-time systems is necessary.
